Baptism is an ordinance of the New Testament, ordained by Jesus Christ. To those baptized it is a sign of their fellowship with him in his death and resurrection, of their being grafted into him (Ro 6:3-5; Col 2:12; Gal 3:27), of remission of sins (Mk 1:4; Ac 22:16), and of submitting themselves to God through Jesus Christ to live and walk in newness of life (Ro 6:4).
Those who personally profess repentance toward God and faith in and obedience to our Lord Jesus Christ are the only proper subjects of this ordinance (Ac 2:41; 8:12, 36-37; 18:8).
The outward element to be used in this ordinance is water, in which the individual is to be baptized in the name of the Father, and of the Son, and of the Holy Spirit (Mt 28:19-20; Ac 8:38).
Immersion, or dipping of the person in water, is necessary for this ordinance to be administered properly (Mt 3:16; Jn 3:23).
