In Mark 16:16 Whoever believes and is baptized will be saved, but whoever does not believe will be condemned.
Who is allowed to baptize another person? Does the Bible provide any details regarding who can perform a baptism?
First, it is obvious that a person who baptizes someone else should be a Christian.
Second, church leaders traditionally baptized people in the New Testament. This was not limited to Elders or Pastors only, but also included missionaries like Paul and his associates who performed baptisms during their missionary activities. The Church leader Philip also baptized an Ethiopian in Acts 8: 36-39.
Third, the Great Commission was originally give to those with Jesus before He ascended to heaven but applies to all believer. Matthew 28:19. Make disciples of all nations, and baptize them in the name of the Father, Son, Holy Ghost.
Fourth, there is no age or gender requirement for those who can baptized others.
Interestingly, Scripture dose not focus very much on the person who baptizes Christians. John 4:2 teaches, “Although Jesus himself did not baptize, but only His disciples.” Jesus had His disciples baptized His followers rather than doing it Himself. – Elder Shaw
