A Christian is defined as any person who follows the Christian religion. This monotheistic religion is based on the belief of a single God, the Lord, who created the world and sent his only son, Christ, to redeem him from his sins. The Christian religion shares this God with Judaism, although the Jews do not accept Christ as the son of the Lord.
According to Christian tradition, the Lord’s son, Christ, also alternatively called Jesus of Nazareth (his birthplace), came into the world to save the human race from the sins naturally committed by it. In very general terms this is what essentially defines a Christian, together with the ideas that Christ is not only the son of the Lord but that he is also God, that he is the Messiah promised in the Old Testament, that he has given his life for human salvation, dying crucified on the cross and that after three days he rose from death to take his triumphant place next to his Father in heaven.
A Christian is then one who believes in all these assumptions and who must also demonstrate his dedication to Jesus from facts such as Baptism, Communion, Confirmation, respect for the Ten Commandments and others that have to do with daily behavior. : attendance at mass, communion of the body of Jesus, maintenance of a life of solidarity and love of neighbor.
Today, Christianity is the religion with the largest number of adherents, estimated to exceed two billion believers worldwide. Within this religion we can include different branches that have been separating over time such as Protestants, Orthodox, Anglicans, Evangelicals, Jehovah’s Witnesses, Quakers and others. All of them, however, are united by the belief in Jesus Christ as the only Son of God.
