Christianity is a major world religion based on the life and teachings of Jesus Christ, who is considered the Son of God by believers. It emphasizes love, compassion, and forgiveness, and its followers, known as Christians, believe in the Holy Trinity: God the Father, God the Son, and God the Holy Spirit. The religion is rooted in the Bible, which is divided into the Old Testament and the New Testament. Christianity has numerous denominations, including Catholicism, Protestantism, and Orthodoxy, each with its own interpretations and practices, but all share a common belief in the core tenets of faith and salvation.
