I thought that a priest could be laicized.
Does not mean what you think it means. Laicised means that certain promises are lifted and obligations relieved so that they return as if to the lay state.
But they are still a priest forever “in the line of melchizadek”-ps 110:4
In an emergency a “Laicised” priest still has to hear confessions.
Technically no, although they can be granted or declared to be in a loss of clerical state for certain matters.
No, getting layed is what got him into trouble in the first place.
