Dear Phil, Why do you feel you need to do a 'penance'? There isn't anything you can personally do to assuage your sins. That's why Jesus went to the cross, he did it for us. Repent yes but penance is not necessary. Jack Temporal Punishment http://www.newadvent.org/cathen/12575a.htm That temporal punishment is due to sin, even after the sin itself has been pardoned by God, is clearly the teaching of Scripture. God indeed brought man out of his first disobedience and gave him power to govern all things (Wisdom 10:2), but still condemned him "to eat his bread in the sweat of his brow" until he returned unto dust. God forgave the incredulity of Moses and Aaron, but in punishment kept them from the "land of promise" (Numbers 20:12). The Lord took away the sin of David, but the life of the child was forfeited because David had made God's enemies blaspheme His Holy Name (2 Samuel 12:13-14). In the New Testament as well as in the Old, almsgiving and fasting, and in general penitential acts are the real fruits of repentance (Matthew 3:8; Luke 17:3; 3:3). The whole penitential system of the Church testifies that the voluntary assumption of penitential works has always been part of true repentance and the Council of Trent (Sess. XIV, can. xi) reminds the faithful that God does not always remit the whole punishment due to sin together with the guilt. God requires satisfaction, and will punish sin, and this doctrine involves as its necessary consequence a belief that the sinner failing to do penance in this life may be punished in another world, and so not be cast off eternally from God. All sins are not equal before God, nor dare anyone assert that the daily faults of human frailty will be punished with the same severity that is meted out to serious violation of God's law. On the other hand whosoever comes into God's presence must be perfectly pure for in the strictest sense His "eyes are too pure, to behold evil" (Habakkuk 1:13). For unrepented venial faults for the payment of temporal punishment due to sin at time of death, the Church has always taught the doctrine of purgatory. So deep was this belief ingrained in our common humanity that it was accepted by the Jews, and in at least a shadowy way by the pagans, long before the coming of Christianity. ("Aeneid," VI, 735 sq.; Sophocles, "Antigone," 450 sq.). end quote. Matthew 12:32 1 Corinthians 3:11-15: "For other foundation no man can lay, but that which is laid; which is Christ Jesus. Now if any man build upon this foundation, gold, silver, precious stones, wood, hay stubble: Every man's work shall be manifest; for the day of the Lord shall declare it, because it shall be revealed in fire; and the fire shall try every man's work, of what sort it is. If any man's work abide, which he hath built thereupon, he shall receive a reward. If any man's work burn, he shall suffer loss: but he himself shall be saved, yet so as by fire." As gold is purified in the fire, so also must most souls be purified, and have their natural sinful nature literally burned out of them before they are perfected enough to enter heaven. Philip. PS It does not matter if you believe it or not... I'm not taking any chances, and a little pesonal sacrifice can do no harm and may save me some worser pain. As the old lady in the crowd said to the 'Catholic' priest preacher who said He did not believe in Hell.. "You'll believe it when you get there"
