Latin church only.FYI, the Byzantine Catholic Churches use “You are absolved”, and that is a valid Sacramental form.
And in the Chaldean Church, the words used are " I forgive" (in Arabic) as the normative form.
So when you mean “The Church”, are you referring to customary practices within one Particular Church, or are you referring to the Catholic Church as a whole.
If you are referring to the Church as a whole, the Church has a wide variety of valid Sacramental forms for absolution.
We had no reason to presume the OP was not dealing with a Latin priest, so we comment based on the law of the Latin church.
I guess that makes me legalistic. That seems to be a favourite word around CAF these days.
