A Jesus emerged from Judaism and established Christianity, the state religion of the Roman Empire.

Rome is divided into West Rome and East Rome (Byzantium). The West is called Catholicism and the East is called Orthodox Church.

Martin Luther divided Protestantism into Catholicism, and there are many factions under Protestantism. Among them, those who come to China are called "Christianity"

Structure:

Catholicism: Pope-clergy-Christians;

Orthodox Church: Patriarch-clergy-Christians;

Protestantism: there is no special level;

Church differences:

Catholic church: mostly in western Europe, there are many statues, Jesus was crucified and there are many statues; There are kneeling stools, confession kiosks, holy water tanks and other equipment;

Orthodox Church: There are many eastern Europe, many portraits and few statues;

Protestantism: there is only one cross, in China, Britain, Australia, the United States or northern Europe; There is no cross on the Christian cross;

The difference between Catholicism and Christianity:

Catholicism has a pope;

Catholicism pays tribute to the virgin Mary, saints, angels, etc. And Christianity does not salute;

Catholicism divides crimes into big crimes and small crimes. The great sin is the sin that deserves to die and makes the soul die, and the small sin is not a deadly sin. Great sins must be forgiven by baptism, repentance and sacrament, while minor sins make people lose God's grace.

Catholicism believes that believers should repent to the priest when they commit a crime, and only through the priest's announcement can they be forgiven. Christianity pays attention to confessing directly to its own Lord. The priest is also a sinner and cannot represent God.

Catholicism believes that the bread and grape juice of the Eucharist, after being blessed, become the real body and blood of Jesus, and Jesus' humanity and divinity are hidden in bread and cups.

The biggest difference between Catholicism and Christianity in doctrine and belief is that Christianity is justified by faith and saved by grace; Catholicism was saved by virtue forgiving sin.

Catholicism pays attention to faith, love and hope in virtue, and believes that besides believing in Jesus, it is necessary to do good things to be saved. And those who don't know Jesus can go to heaven as long as their life and behavior meet the standards of Christians.

Christianity emphasizes justification by faith, which means that as long as you believe, you can be saved. If you don't believe me, you will go to hell.

Christianity calls the regular worship activities worship god, which is flexible and diverse in form, and preaching is a main content; The main worship activity of Catholicism is mass to commemorate the crucifixion and sacrifice of Jesus. The program is completely fixed. The priest attends mass every day, and there are no lectures except the main mass.

Catholicism believes that besides the Bible, there are sacraments, because it is impossible to completely record all the words and deeds of the Lord by the Bible alone. Christianity believes that only the Bible can be trusted, and there is no authority except the Bible. Because God wrote all the revelations in the Bible.

Catholicism pays attention to collective interpretation, that is, to interpret the Bible through collective discussion and interpretation, and then publish the results. So Catholics all over the world have the same understanding of the Bible.

Christianity stresses free interpretation of the Bible, and everyone understands the Bible according to his own ideas. If you think your understanding is correct and different from others', you can start a new sect by yourself. So Christianity is not a religion, but a bunch of sects. According to previous statistics, there are more than 8,000 sects, and their understanding of the Bible is different.

Catholicism believes that there are heaven, hell and purgatory. Some people have committed some minor crimes and can still enter heaven after being purified in purgatory. Christianity only recognizes heaven and hell, and there is no other opportunity to go directly to heaven or hell.

There are seven sacraments in Catholicism, namely baptism, confirmation, communion, confession, ordination, anointing and marriage. All Christian sects have baptism sacraments, but there are no collective sacrifices or other sacraments.
