He did so not only to to the apostles, but that meeting also included other disciples, as context indicates, (Mt. 18:18; Jn. 20:23) and it does not mean God must subscribe to any sentence of the priest (besides NT pastors never distinctively being called priests).
Ill take Christs words any day over Pauls words.
As if one had to. A very revealing statement testifying to the opposition RCs see btwn the gospels and Paul, and preference they have for the former, as they see them supporting Rome more, as they are in theologically need of explanation, which Christ promised, and which the epistles are, without which we would lack much.
The Gospels are first hand acconts. When did Paul meet Jesus except in being blinded on the way to Damascus?
Fact is — in the bible — Paul persecuted the Christians and did not meet Jesus and have first hand information.
