A MAP OF LIFE not know he cannot teach. But in no case can he teach what is wrong: for God will not let him, lest we, the members of the Church, be led into error. One further thing remains to be said. We believe what the Church teaches because the Church is the Mystical Body of Christ, because, therefore, her teaching is the voice of Christ Himself. Among the mass of the things she teaches and the moral laws she propounds, some are, as it were, easy for the human mind, some difficult. For some we seem to see a score of reasons, for some we see no reason at all, some actually might seem to us against reason. But all alike we accept on the one secure ground — that the Church teaches them. We do not accept the easy ones because we can see why, and the others only by an act of Faith. We accept the easy ones — because the Church teaches them; and we accept the difficult ones — because the Church teaches them. When a doctrine or a moral law is presented to us we may ask what are the reasons for it, but only that we may the better comprehend it, not that we may decide whether or not to obey it. For that we only ask does the Church teach it. For it is thus that Christ would have us know the Truths by which our lives are to be lived. 76
