Baptism:

Baptism within the Lutheran Church:​
​

 Although Luther retained that baptism was necessary for spiritual regeneration, no specific form was stipulated. Today Lutherans practice both infant baptism and baptism of believing adults. Baptism is done by sprinkling or pouring water rather than immersion. Most Lutheran branches accept a valid baptism of other Christian denominations when a person converts, making re-baptism unnecessary.
