There’s a lot of differences between Christian denominations, but for now we’re starting with Catholicism vs. Protestantism. If you aren’t a Christian, you may be confused about why there’s a lot of Christian infighting, and that can be boiled down to, “a guy just decided x thing from x denomination is bad!”
Protestantism was notoriously pioneered by Martin Luther, a former German monk. Likely there were others at the time, but he was most notable due to his 95 Theses criticizing the Catholic Church, especially the sale of indulgences*. He believed and argued that salvation comes through faith alone, not good works. His protest spread across Europe and led to new Christian groups breaking away from the Roman Catholic Church.
Before the Catholic Bible was officially confirmed at the Council of Trent in 1546, the Church already recognized most of its books as Scripture. Yet Martin Luther disputed several of those books and wrote a number of opinion pieces about Christian teaching, the Church, and related matters. Luther sent his theses to his direct superior, Archbishop Albrecht, and Pope Leo X tasked theologians with examining Luther’s arguments, not only to refute him but also to see which of his points might have merit. The Church objected to only 41 of the 95 theses and asked Luther to recant the writings that were wrong; when he refused, he was excommunicated.
For the rest, the Church made changes in line with the parts of Luther’s theses that were considered accurate. Luther’s 1517 challenge to papal authority and Catholic doctrine helped spark the Reformation, a movement that eventually led to the creation of more than 30,000 Christian denominations, many breaking away not only from the Catholic Church but also from one another over even small differences in interpreting theology.
There are also other reasons people use to discredit Luther’s opinions, such as pointing out that he married a nun. This later influenced many Protestant traditions to allow clergy marriage, since Reformers generally agreed with his criticism of compulsory celibacy.
If the Catholic Church was not the true Church and Martin Luther broke away from it, then how could Luther’s movement claim to be the correct Church if no true Church existed prior to him? If the pre-Luther Church was considered false, that would seem to imply there was no valid apostolic succession to pass on, as referenced in passages like 1 Timothy. And if the Church Luther left was not truly the Church Christ established, it raises the question of where his authority originated. In that case, the Protestant Church would appear to have emerged without historical continuity. So if Protestantism is true, where was it before the Reformation? How can it claim to be the continuation of the true Church if it only appears after the Catholic Church historically? - St Francis de Sales, the Catholic Controversy
Catholics have 7 sacraments, Protestants have 2 sacraments. Even the "closest to Catholicism" Lutheran Protestants
Catholics and Protestants do worship the same God. We have the same books, mostly same fundamental beliefs, but we differ significantly on doctrines and practices. When I was considering Orthodoxy, Catholicism, or staying Protestant I was mainly focused on something I felt like was a big part of my personal beliefs:
I knew that the filioque was true (most Protestants historically accept the Filioque clause), and the
immaculate conception obviously isn't a protestant theological belief but when I read
Exodus 40:35, Moses could not enter the tent of meeting (tabernacle) because the cloud of God’s glory rested
on
it
and
filled the interior. Jesus Christ is considered the supreme revelation and
embodiment of the glory of God. Mary physically could not have Jesus if she was sinful. She was Graced for
God's
plan. This isn't a Protestant belief, at all. But some Protestants do personally have beliefs outside of
their denominations doctrine.
Protestants reject the veneration of Mary, since they confuse it as worship.
I just want to say that if you don't believe in the Holy Trinity, the Holy Bible, that Jesus is fully God & fully divine then you don't follow Christianity or the Christian God at all. Abrahamic religions just get lumped together as similar (Judaism & Islam, but there's also several other faiths that are classified as Abrahamic) all the time, but we're really different and do not worship the same God. The only reason I can sit here and outline Protestant V.S Catholicism is because Protestants branched off Catholics, and do believe in the same God.
A sacrament is a Christian ritual set by Jesus Christ that serves as an external, visible expression of an internal, spiritual grace. Catholics have 7 while Protestants have 2. (May be 3 or so, depending on denomination)
Baptism (often called christening for infants) is a Christian ceremony that uses water, by pouring, sprinkling, or immersion, to represent cleansing, new life, and joining the Church. For babies, it is a sign that the parents are committing to raise the child in the Christian faith. For adults, it shows a personal decision to repent and choose to follow Christ. Catholics view this as necessary for our salvation, and believe that it actually confers grace, removes original and personal sin.
Protestants view baptism, and many other of our sacraments as symbolic, and some protestant denominations do not allow infant baptism.
After Baptism, you go through confirmation. It's a sacrament that strengthens the personal faith and grace you receive at baptism. It is usually done by a bishop or priest laying hands on the person and anointing them with oil. It represents the Holy Spirit giving them strength to live out their faith more fully and to stand firm in their beliefs.
For protestants, this is not a sacrament. Some protestants (Anglican, Lutheran) retain a confirmation-like rite, while others often see it as a personal profession of faith rather than sacramental grace.
Catholics believe in transubstantiation, meaning the bread and wine become the Body and Blood of Christ. They believe Christ is truly and substantially present in the Eucharist, and it is central to Catholic worship.
If you do not believe in transubstantiation, it means that you believe the wine is simply wine and the bread is simply bread.
Most Protestants see the Eucharist differently. Many view it as symbolic, remembering Christ’s sacrifice, while others believe in a spiritual presence rather than a physical change, so they still deny transubstantiation.
There are several reported Eucharistic miracles in which bread and wine are said to have transformed into flesh and blood. Some of these have been preserved as relics and examined in scientific studies, which are often reported as identifying them as human heart tissue and type AB blood.
In Catholic teaching, confession to a priest is based on passages where Jesus gives the Apostles authority to forgive sins (for example John 20:21–23). Catholics believe this authority continues through apostolic succession, so priests act in that role when hearing confessions.
People can still confess sins directly to God or talk to trusted people for support, but Catholics believe a priest has a unique role that others do not. The priest is meant to give spiritual guidance, not judge the person, and must keep everything strictly confidential through the “seal of confession.” Catholics also believe that, through this sacrament, the priest gives absolution in Christ’s name, which others cannot do.
Both Catholics and Protestants agree that confessing sins to others is biblical, but Catholics also practice a formal sacramental confession to a priest with absolution.
The Anointing of the Sick is a Catholic sacrament given to people who are seriously ill, elderly, facing major surgery, or in serious physical or mental distress.
A priest visits the person and prays over them, usually laying hands on them and anointing their forehead and hands with blessed oil called the Oil of the Sick. The prayers ask God for healing, peace, and strength.
Most Protestant traditions do not treat anointing as a sacrament, and it is seen as a symbolic act of prayer and faith rather than a sacrament that guarantees grace. Prayer for the sick is practiced in all churches, but it is not considered a required or sacramental rite.
Holy Orders is the Catholic sacrament through which a man is ordained to serve the Church as a deacon, priest, or bishop. These roles are believed to carry grace and spiritual authority for sacred duties, including celebrating Mass (Eucharist), forgiving sins in Confession (priests and bishops), preaching and teaching the Gospel, and leading and serving the Church community.
Protestants reject sacramental priesthood, ministers/pastors are seen as leaders or teachers, not sacramental mediators. Some traditions (Anglican, Lutheran) retain ordination but not the Catholic understanding of sacrament
Catholics see marriage as a sacrament between a baptized man and woman. It represents Christ’s union with the Church and is meant to last for life.
The Church does not recognize divorce as ending a valid sacramental marriage. However, civil divorce or separation is allowed in serious situations like abuse or danger, and many would suggest having the marriage absolved (legally claim that it never happened via judge) instead.
Protestants view marriage as a sacred covenant, but not a sacrament in most traditions. Marriage is still very important spiritually, but not seen as conferring grace in the sacramental sense, and divorce rules vary. In my experience with Protestant churches, they'll 'allow' it but judge you and gossip. A lot.
Catholicism still practices indulgences obtained through specific pious acts like prayer, confession, Communion, and good works, offering a lessening of temporal punishment for sins already forgiven, not salvation itself. Back then, indulgences were sometimes misunderstood as being like currency, and this was later corrected. This is where the argument that “Catholics will pay for their sins to be absolved” comes from.
Saints show that ordinary humans can follow the narrow path to heaven and imitate Jesus. We can’t all relate to Jesus’ perfect life, but Saints show that imperfect humans can still live faithfully.

It is wrong to describe Catholic veneration of saints as "praying to the dead" if one truly believes in the doctrine of eternal life with Christ. This argument highlights a basic contradiction: if the saints are truly alive in Christ, then asking for their intercession is a recognition of the faithful who are united with God beyond death rather than an appeal to the dead. It implies a misinterpretation of the communion of saints to hold both perspectives at the same time.
Catholics ask Mary to intercede, like asking a friend to pray for you, which is ultimately relying on Christ.A large amount of Protestants accuse Catholics of being idolators, meanwhile a 22-foot gold statue of Donald Trump, titled "Don Colossus," was unveiled at the Trump National Doral Miami golf course by a group of cryptocurrency investors and dedicated by evangelical leaders in May 2026. A lot of Protestants like Trump, and almost borderline worship Israel since they have not mentally processed what the Book of Romans was about! Catholic Saints point to Jesus, so why is Donald Trump pointing to Israel?
Many people use 1 Timothy 2:11–12 to argue that God is misogynistic, but it's Paul that's the one who tells women that they have no authority over the Church clergy. False teachings and religious confusion were common among the women of Ephesus, where Paul was ministering. In that specific church, women were interjecting and disseminating ignorant doctrines or influences from pagan cults. It is also difficult to reconcile the honor given to Mary with the belief that Christianity fundamentally disregards women, particularly in the more traditional Christian denominations. Mary is the most revered human being in Catholicism and Orthodoxy, and many female saints have been acknowledged as important spiritual leaders and teachers in the Church.
First Epistle to Timothy 2:13–14 is a reference to the creation and Fall story in the Book of Genesis, not a claim that women are the cause of sin in the world. Paul is using Genesis to explain his point about order and deception, the summary in Timothy is taken out of context all the time to fit a narrative that is ignorant.
The Bible often describes Adam as the representative of humanity, especially in Epistle to the Romans 5:12–19 and First Epistle to the Corinthians 15:21–22, where sin and death are said to enter through “one man,” who is Adam. Catholic theology often emphasizes that Eve was deceived, while Adam was not deceived in the same way since he knowingly disobeys.
Religious abuse (using it to justify hate on any of the -phobics or race) is a sign of human failure rather than a refutation of religion. Catholic teaching explicitly states that every human person has equal dignity because they are made in God’s image (Book of Genesis 1:27), and discrimination based on race or ethnicity is morally wrong. Unjust treatment of women especially contradicts the Christian moral teaching.
Luke 8:1–3 — women travel with Jesus and financially support His ministry
Luke 10:38–42 — Mary (Martha’s sister) sits at Jesus’ feet as a disciple, learning like a student, showing women are included in discipleship and teaching contexts
John 4:7–26 — Jesus speaks with a Samaritan woman (a social taboo at the time) and engages her in deep theological discussion
John 20:16–18 — Mary Magdalene is the first witness of the Resurrection and is sent to proclaim it (despite women not normally holding that role in that culture)
Romans 16:1–7 — Paul commends Phoebe (a deacon/servant), Priscilla (teacher), and Junia (noted among the apostles)
Judges 4–5 — Deborah is a judge, prophet, and leader of Israel
Exodus 15:20–21 — Miriam is a prophetess who leads Israel in worship
The claim that “religious places are less advanced than places that value science” is misleading and oversimplified. Major religious centers can also have highly developed engineering, medical, and educational systems, like Rome. In some cases, there may be a weak link between scientific advancement and lower religiosity, but correlation is not the same as causation. Societies are complex, so development cannot be explained by just one factor.
A key consideration is education. There is evidence that different religious groups have different levels of education and religiosity, but this varies a lot and is strongly influenced by social and historical factors rather than religion alone. For example, differences in education levels among religious groups may reflect migration patterns, community structure, or historical access to education. In some cases, higher education is linked more to certain demographics or job fields rather than belief systems themselves.
We also notice that in many countries where religion is considered highly important, it is often closely tied to society and culture rather than just personal belief. Many of these countries are in Africa, Asia, and Latin America, often shaped by colonial history and development paths. On the other hand, places like Cuba and China rank high in irreligion partly due to socialist and anti-religious political history, not simply because they are “more advanced.” Uruguay also stands out in Latin America, but this is likely connected to its regional and historical background rather than religion alone.
The bottom line is that these kinds of comparisons must consider geographical, political, and cultural contexts before drawing conclusions based only on religion. Country-wide comparisons can be misleading because religion interacts differently in each society. The real relationship between religion and development is complex and changes over time as societies evolve.
Everyone probably knows the story of Genesis, tdlr: it's about the creation of earth and the fall of mankind. periods weren't designed as punishment for women because of Eve sinning but is a necessary process for fertility so that Eve could produce a new bloodline for the New Adam (Jesus)
Nothing evil is ever ignored, excused, or left unresolved by God’s justice. However, when people raise this argument, they’re usually talking about serious perpetrators like rapists, killers, abusers, and the like. The claim is essentially: “Would an all-loving God allow a victim and their abuser to be in heaven together just because the abuser repented?”
From a Catholic perspective, this misunderstands what repentance and heaven actually are. Repentance is not a loophole or a way to “trick” God into acceptance, it is a real and total conversion of the person. And nobody can deceive God or manipulate His judgment, because He fully knows what is in the human heart with perfect clarity. Heaven is not a place where evil relationships continue unchanged or are simply ignored; it is where all injustice is fully judged, healed, and transformed in the light of God’s truth.
A lot of Christians say, "do not judge others, God sees the sin as the same!" and while that is true, it's an oversimplication of the teaching. Catholic teaching actually does distinguish between sins in terms of gravity. For example, consensual fornication is considered sinful because it misuses sexuality outside of marriage. However, acts like assault, rape, torture, murder, and abuse are far graver because they directly violate justice, charity, and human dignity, and often cause severe or lasting harm to another person.
Therefore, fornication and murder are not morally identical, even though they may both involve "grave matter" depending on the circumstances. Catholicism acknowledges actual variations in sin severity rather than reducing all sins to the same degree of evil. This distinction is also reflected in Scripture. Jesus talks about varying degrees of judgment and "greater sin." In John 19:11, Jesus says to Pontius Pilate:
11 Jesus answered [him], “You would have no power over me if it had not been given to you from above. For this reason the one who handed me over to you has the greater sin.”According to Catholic interpretation, this shows that even in cases where multiple people are involved in wrongdoing, guilt can vary. Jesus explicitly defines a "greater sin" and does not hold each person equally accountable for different sins.
In a similar vein, Luke 12:47–48 teaches that knowledge and responsibility are correlated with punishment, meaning that moral culpability rises with increased awareness and conscious decision-making.
In conclusion, Catholic teaching maintains that while all mortal sins cause a person to become distant from God, not all sins are of the same seriousness, intent, or harm.Sources
