Yes, there is even in ourselves sin and corruption enough, so that there is no need that God should infuse into us either a new or greater measure of wickedness. Therefore, when God is said in the Scripture to harden (Ex. 7:13), to blind (John 12:40) and to deliver us up into a reprobate sense (Rom. 1:28), it is to be understood that God does it by just judgment, as a just judge and avenger.

However, we cannot in any way acknowledge or accept what our opponents openly say, namely that Mary is to be invoked as a mediator between God and humans, or that she is our patron and advocate. We do not believe that this is either a tradition of Holy Scripture or a command from God. We believe that God, who alone grants all salvation for the present and future, is the one to be invoked alone. We believe that Christ alone [since He alone is true God and true man] is the true mediator between God and humans. We believe that He, who alone can satisfy all humans, is the patron and advocate with the Father.
