Baptism: Becoming a Christian

The Sacraments of Initiation—Baptism, Confirmation, and the Eucharist—are the foundations of the Christian life.

Are you unaware that we who were baptized into Christ Jesus were baptized into his death? We were indeed buried with him through baptism into death, so that, just as Christ was raised from the dead by the glory of the Father, we too might live in newness of life. —Rom 6:3-4

Baptism is birth into the new life in Christ. In accordance with the Lord’s will, it is necessary for salvation, as is the Church herself, which we enter by Baptism. —CCC, no. 1277
