This is a theological analysis of the Catholic doctrine of sacramental intention and it's application to the claim that the Holy Orders of Archbishop Lefebvre, along with all those who derive their Orders from him, are invalid or doubtfully valid, due to the possibility that Lefebvre's ordaining and consecrating bishop, Cardinal Lienart, was a Freemason.

This analysis provides Catholic principles and teachings showing that whether or not Cardinal Lienart was a Freemason is irrelevant to the validity of Orders conferred or received by him, and that Catholics are obliged to presume these Orders are valid.
