WHY DO WE MAKE THIS PETITION?

It must be known that from this petition we can draw two things that are necessary for us in this life. One is that we be ever in a state of salutary fear and humility. There have been some, indeed, so presumptuous as to say that man could live in this world and by his own unaided strength avoid sin. But this condition has been given to no one except Christ, who had the Spirit beyond all measure, and to the Blessed Virgin, who was full of grace and in whom there was no sin. "And concerning whom," that is, the Virgin, "when it is a question of sin I wish to make no mention," says St. Augustine.⁵ But for all the other Saints, it was never granted them that they should not incur at least venial sin: "If we say that we have no sin, we deceive ourselves and the truth is not in us."⁶ And, moreover, this very petition proves this; for it is evident that all Saints and all men say the "Our Father" in which is contained "Forgive us our trespasses." Hence, all admit and confess that they are sinners or trespassers. If, therefore, you are a sinner, you ought to fear and humble yourself.

Another reason for this petition is that we should ever live in hope. Although we be sinners, nevertheless we must not give up hope, lest our despair drive us into greater and different kinds of sins. As the Apostle says: "Who despairing, have given themselves up to lasciviousness, unto the working of all uncleanness."⁷ It is, therefore, of great help that we be ever hopeful; for in the measure that man is a sinner, he ought to hope that God will forgive him if he be perfectly sorry for sin and be converted. This hope is strengthened in us when we say: "Forgive us our trespasses."

The Novatiani destroyed this hope, saying that one who has sinned but once after Baptism can never look for mercy. But this is not true, if Christ spoke truly when He said: "I forgave thee all the debt, because thou besoughtest Me."⁸ In whatsoever day, therefore, you ask, you can receive mercy if with sorrow for sin you make your prayer. Both fear and hope arise from this petition. For all sinners who are contrite and confess their guilt, receive mercy. Hence, this petition is necessary.
