Does The United Methodist Church accept the baptism of other denominations?
Yes, The United Methodist Church recognizes the baptism of other Christian denominations. We do not rebaptize those who have already received Christian baptism in any form.
The Book of Discipline says, "A member in good standing in any Christian denomination who has been baptized and who desires to unite with The United Methodist Church may be received as either a baptized or a professing member by a proper certificate of transfer from that person's former church, or by a declaration of Christian faith, and upon affirming willingness to be loyal to The United Methodist Church; It is recommended that instruction in the faith, work, and polity of the Church be provided for all such persons."
