I have generally had good experiences in confession, whether NO, FSSP, or Eastern Rite. I have received bad advice, or at least advice I thought was bad. However, I have never had occasion to question the validity of the absolution I received, nor have I ever been told that it was okay to violate any Church teaching. I am as selective as I can be about confessors, however, and I have a pretty good group to choose from. Not everyone is so fortunate.
