I have a friend who has recently become involved in Protestant Christianity. She has asked me, along with two of her other friends, to baptize her. I’m not sure how three people can perform one baptism, but it’s my understanding that this would be a valid Trinitarian baptism done through the Protestant church that she recently began attending.
I believe the Church teaches that laypeople should only perform baptisms when they need it to be performed immediately and a priest is unavailable, and that an adult should not, under ordinary circumstances, be baptized without having gone through the catechumenate. In this scenario, the person desires to be baptized, but not to be baptized by a priest or to be educated in the Catholic faith.
Is it inappropriate, then, for a Catholic layperson to participate in, or even attend, a Protestant baptism?
(If this question has already been addressed, I apologize–I have searched the forum and not found an exact answer, but if I could be directed towards one, that would be appreciated.)
