Tertullian

“ I praise their fear, I love their reverence; they are unwilling a second time to be a burden to the divine mercy; they fear to seem to trample on the benefit which they have attained; they shun, with a solicitude which at all events is good, to make trial a second time of that which they have once learned to fear. ”

“ If the Lord’s indulgence grants you the means of restoring what you had lost, be thankful for the benefit renewed, not to say amplified; for restoring is a greater thing than giving, inasmuch as having lost is more miserable than never having received at all. However, if any do incur the debt of a second repentance, his spirit is not to be forthwith cut down and undermined by despair. Let it by all means be irksome to sin again, but let not to repent again be irksome: irksome to imperil one’s self again, but not to be again set free. ”

“ Far be it that any one so interpret our meaning, as if, because there is an opening for repenting, there were even now, on that account, an opening for sinning; and as if the redundance of celestial clemency constituted a licence for human temerity. Let no one be less good because God is more so, by repeating his sin as often as he is forgiven. Otherwise be sure he will find an end of escaping, when he shall not find one of sinning. We have escaped once: thus far and no farther let us commit ourselves to perils, even if we seem likely to escape a second time. ”
