Hence St. Bernard says, that "whatever a man, holding the place of God commands, provided it be not certainly sinful, should be received as if the command came from God himself" (de Præcep. et Discep., cap. xi.). Gerson relates, that the same St. Bernard ordered one of his disciples, who, through scruples, was afraid to say Mass, to go, and trusting in his advice, to offer the holy sacrifices. The disciple obeyed, and was cured of scruples. Some, adds Gerson, will say: ”Would to God that I had a St. Bernard for my director: my confessor is not a St. Bernard." Whosoever you are that speak in this manner, you err; for you have not put yourself under the care of man because he is learned, but because he is placed over you. Obey him, then, not as a man, but as God. (Tract, de Prsop. ad Miss.) You have intrusted the care of your soul to a confessor, not because he is a man of learning, but because God has given him to you as a guide; and, therefore, you ought to obey him, not as a man, but as God.
6. ”An obedient man shall speak of victory." (Prov. xxi. 28.) Justly, says St. Gregory, has the Wise Man asserted, that they who are obedient shall overcome the temptations of hell: because, as by their obedience, they subject their own will to men, so they make themselves superior to the devils, who fell through disobedience. "The obedient are conquerors; because, whilst they subject their will to others, they rule over the angels that have fallen through disobedience" (in lib. Beg., cap. x.) Cassian teaches, that he who mortifies self-will beats down all vices; because all vices proceed from self-will. “By the mortification of the will all vices are dried up." He who obeys his confessor, overcomes all the illusions of the devil, who sometimes makes us expose ourselves to dangerous occasions under pretext of doing good, and makes us engage in certain undertakings which appear holy, but which may prove very injurious to us. Thus, for example, the enemy induces certain devout persons to practise immoderate austerities, which impair their health; they then give up all mortifications, and return to their former irregularities. This happens to those who direct themselves; but they who are guided by their confessor are not in danger of falling into such an illusion.
