“”Once we’re forgiven, the sin debt is gone.””
Our sins effect fellow man and our sins can cause fellow man to sin against others because of what we did.
Those who don’t believe in penance are self centered and are truly not sorry or they could care enough to do penance for the sins against fellow man by acting Christ like and imitating Him
Basically,denying penance is being a lazy sinner
MM-””Penance is not Scriptural.””
“And you have forgotten the consolation, which speaketh to you, as unto children, saying: My son, neglect not the discipline of the Lord; neither be thou wearied whilst thou art rebuked by him.
[6] For whom the Lord loveth, he chastiseth; and he scourgeth every son whom he receiveth. [7] Persevere under discipline. God dealeth with you as with his sons; for what son is there, whom the father doth not correct? [8] But if you be without chastisement, whereof all are made partakers, then are you bastards, and not sons. [9] Moreover we have had fathers of our flesh, for instructors, and we reverenced them: shall we not much more obey the Father of spirits, and live? [10] And they indeed for a few days, according to their own pleasure, instructed us: but he, for our profit, that we might receive his sanctification.
[11] Now all chastisement for the present indeed seemeth not to bring with it joy, but sorrow: but afterwards it will yield, to them that are exercised by it, the most peaceable fruit of justice. [12] Wherefore lift up the hands which hang down, and the feeble knees, [13] And make straight steps with your feet: that no one, halting, may go out of the way; but rather be healed” Heb 12:5-13
Instead of penance every time you commit the sin, how about repenting and not doing it any more?
Or don't you think that that doesn't show that someone is sorry enough for their sin or that they don't care enough?
