3. What is Christianity? Christianity is a monotheistic religion centered on the life and teachings of Jesus as presented in the New Testament.

4. Jesus Christ The focus of a Christian's life is a firm belief in Jesus as the Son of God and the "Messiah" or "Christ". The title "Messiah" comes from the Hebrew word מָשִׁיחַ (mā š i á ħ) meaning anointed one. The Greek translation Χριστός (Christos) is the source of the English word "Christ"

5. Christians believe that, as the Messiah, Jesus was anointed by God as ruler and savior of humanity, and hold that Jesus' coming was the fulfillment of messianic prophecies of the Old Testament. The core Christian belief is that, through the death and resurrection of Jesus, sinful humans can be reconciled to God and thereby are offered salvation and the promise of eternal life.

7. Bible Christianity regards the Bible, a collection of canonical books in two parts (the Old Testament and the New Testament), as authoritative.
