“We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life.” — Romans 6:4
Christian baptism, being the believer’s profession of faith, is an act of obedience symbolizing the believer's faith in a crucified, buried, and risen Savior, the believer's cleansing from sin and death to sin, the burial of the old life, and the resurrection to walk in newness of life in Christ Jesus. It is to be done by immersion in water in the name of the Father, the Son, and the Holy Spirit.
Being a church ordinance, it is prerequisite to the privileges of church membership. The Lord's Supper is a symbolic act of obedience whereby members of the church, through partaking of the bread and the cup, remember the death of the Redeemer and anticipate His second coming.
