BAPTISM.
Christ was baptized Himself. He told John it was necessary for Him "to fulfill all righteousness." He taught that it was necessary for all men to be baptized.
"Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God." (John 3: 5).
"He that believeth and is baptized shall be saved." (Mark 16: 16).
Christ's disciples also taught the same. When those who believed Peter's preaching on the day of Pentecost asked what they should do to be saved, he replied,
"Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost." (Acts 2: 38).
These passages of scripture prove that Jesus and His disciples taught baptism.
