It is ordained that confessions be made carefully, especially of mental disturbances, before going to Mass, lest perhaps any should approach the altar unworthily, that is, if he does not have a clean heart. For it is better to wait until the heart is healed, and becomes a stranger to offence and envy, than rashly to approach the judgement of the throne. For Christ's throne is the altar, and His Body there with the Blood judges those who approach unworthily. Therefore, just as we must beware of mortal and fleshly sins before we communicate, so we must refrain and cleanse ourselves from interior vices and the sicknesses of a drooping spirit, before the covenant of true peace and the bond of eternal salvation.
