Highest Catholic Population 2023
Catholicism is a religion practiced in nations all around the world. It's a division of Christianity, the largest religion globally. There are several core beliefs of Catholicism. First, Catholics believe that Jesus is the son of God, that he was put to death by crucifixion sometime around 33 CE, and that he rose from the dead and ascended into Heaven. Catholics also believe that the Bible is the word of God. Catholics use the Ten Commandments as a moral and ethical compass. Catholics believe in Adam and Eve, and they believe that all humans are sinners because of Adam and Eve's original sin.
While these basic beliefs are common amongst all variations of Christianity, Catholicism also holds a number of exclusive views unique among Christian denominations. For example, while most Christians view baptism as a symbolic act, Catholics believe that the practice removes this original sin and is necessary for salvation. In addition, Catholics value praying to deceased saints and the Virgin Mary, whereas Christians pray only to the Holy Trinity of the Father (God), the Son (Jesus), and the Holy Spirit. Additional differences include Catholics' confession of sins to an Earthly priest and the Catholic belief in the existence of Purgatory.
