Baptism is the basis of the whole Christian life, as we are born of the water and the Spirit. Baptism is necessary for salvation (John 3:5), and conveys a permanent sign that the new Christian is a child of God. Jesus himself was baptized in the Jordan River by Saint John the Baptist (Mark 1:9-11). Baptism is prefigured in the Old Testament through the saving of Noah and his family during the Flood (Genesis 7:12-23, 1 Peter 3:20-21), and Moses crossing of the Red Sea during the Exodus, leaving captivity for the Promised Land (Exodus 14:1-22).
The Greek word "baptizein" means to "immerse, plunge, or dip." The infant or candidate is anointed with the oil of catechumens, followed by the parents, godparents, or candidate making the profession of faith. The essential rite of Baptism consists of the minister immersing the baby or person in water or pouring water on his head, while pronouncing "I baptize you in the name of the Father, the Son, and the Holy Spirit." The infant or candidate is then anointed with sacred chrism.
What has taken place in Baptism is indicated by the rites that follow it, the clothing in the white garment and giving of the lighted candle: the baptized person has "put on Christ" and has now become light. Here are three Scriptural sources in the New Testament (See also Matthew 3:13-17, Luke 3:21-22; Acts 1:21-22; Romans 6:3-4; Ephesians 4:5; Colossians 2:11-13, I Peter 3:21)
