Contrition, which holds the first place among the aforesaid acts of the penitent, is a sorrow of mind and a detestation for sin committed with the purpose of not sinning in the future.[16] This feeling of contrition was at all times necessary for obtaining the forgiveness of sins and thus indeed It prepares one who has fallen after baptism for the remission of sins, if it is united with confidence in the divine mercy and with the desire to perform the other things that are required to receive this sacrament in the proper manner. The holy council declares therefore, that this contrition implies not only an abstention from sin and the resolution and beginning of a new life, but also a hatred of the old,[17] according to the statement: <Cast away from you all your transgressions by which you have transgressed, and make to yourselves a new heart and a mew spirit.>[18] And certainly he who has pondered those lamentations of the saints: <To thee only have I sinned, and have done evil before thee;[19] have labored in my groanings, every night I will wash my bed;[20] I will recount to thee all my years in the bitterness of my soul,>[21] and others of this kind, will easily understand that they issued from an overwhelming hatred of their past life and from a profound detestation of sins. The council teaches furthermore, that though it happens sometimes that this contrition is perfect through charity and reconciles man to God before this sacrament is actually received, this reconciliation, nevertheless, is not to be ascribed to the contrition itself without a desire of the sacrament, which desire is included in it. As to imperfect contrition, which is called attrition, since it commonly arises either from the consideration of the heinousness of sin or from the fear of hell and of punishment, the council declares that if it renounces the desire to sin and hopes for pardon, it not only does not make one a hypocrite and a greater sinner, but is even a gift of God and an impulse of the Holy Ghost, not indeed as already dwelling in the penitent, but only moving him, with which assistance the penitent prepares a way for himself unto justice.
