Why? In the natural world, anyone can apply a bandage, does that make us all doctors?
I don't know the Catholic doctrine, this is why I asked. So baptism is limited to anyone using the Trinitarian formula. What can not be performed by lay people?
So baptism is limited to anyone using the Trinitarian formula.No, it is more limited - for a complete exploration of the subject, see Baptism
At the outset we think it advisable to give two documents which express clearly the mind of the Church on the subject of baptism. They are valuable, also, as containing a summary of the main points to be considered in the treatment of this important matter. Baptism is defined positively in the one and negatively in the other.In Catholic teaching, Baptism is one of the Seven Sacraments (outward signs of inward grace, instituted by Christ for our sanctification) that Our Lord gave us. All require the correct intent, matter and form. All require the ability to form that correct intent so I doubt that an idiot, incompetent or child can be an extraordinary minister of the Sacrament of Baptism.
