26 But the Church, not content with pointing out the remedy, also applies it. For the Church does her utmost to teach and to train men, and to educate them and by the intermediary of her bishops and clergy diffuses her salutary teachings far and wide. She strives to influence the mind and the heart so that all may willingly yield themselves to be formed and guided by the commandments of God. It is precisely in this fundamental and momentous matter, on which everything depends that the Church possesses a power peculiarly her own. The instruments which she employs are given to her by Jesus Christ Himself for the very purpose of reaching the hearts of men, and drive their efficiency from God. They alone can reach the innermost heart and conscience, and bring men to act from a motive of duty, to control their passions and appetites, to love God and their fellow men with a love that is outstanding and of the highest degree and to break down courageously every barrier which blocks the way to virtue.
