Christianity is a global religion centered on the life and teachings of Jesus Christ, who followers believe is the Son of God. It's a monotheistic faith, meaning Christians believe in one God who exists in three co-equal persons: God the Father, God the Son (Jesus Christ), and the Holy Spirit. Christianity is based on the Bible, with the Old Testament and New Testament serving as sacred texts.

Paganism is a term first used in the fourth century by early Christians. It was applied on populations of the Roman Empire who practiced polytheism, either because they were increasingly rural and provincial relative to the Christian population or because they were not milites Christi (soldiers of Christ). Alternate terms in Christian texts for the same group were hellene, gentile, and heathen. Pagan and paganism were pejorative terms for the same polytheistic group, implying its inferiority. Paganism has broadly connoted the "religion of the peasantry", and for much of its history was a derogatory term. Both during and after the Middle Ages, pagan was a pejorative term that was applied to any non-Abrahamic or unfamiliar religion, and the term presumed a belief in false god(s).
