The Act of Perfect Contrition
‘As explained by the Baltimore Catechism, contrition ‘is sincere sorrow for having offended God, and hatred for the sins we have committed, with a firm purpose of sinning no more’, and, perfect contrition ‘is that which fills us with sorrow and hatred for sin, because it offends God, who is infinitely good in Himself and worthy of all love.’
