In the Catholic Church, there are three forms of baptism that are considered valid: immersion, pouring, and sprinkling, the last of which is commonly referred to as baptism by aspersion. Among the three valid forms, aspersion is not permitted in the Church today, but it is considered valid. In legal terms, we would say baptism by aspersion is valid but not licit (permitted). Immersion and pouring are both valid and licit.
Baptism is a staple of the Faith, so does my Protestant friend make any valid points here? Well, obviously not when it comes to everybody leaving the Church Jesus established. But what about her point about baptism by immersion?
