ACC ~ 1 John 1 v10
DISTINGUISHING SMALL LAPSES FROM MORTAL SINS. JOHN CASSIAN: Among holy men it is impossible not to fall into those small lapses which occur because of something said, some thought, some surreptitious act. These sins are quite different from those which are called mortal, but they are not without blame or reproach. CONFERENCE 11.9.
NONE SINLESS. AUGUSTINE: Who is there on earth without sin? Even a baby has contracted it from its parents. SERMONS 181.1.
WE MAKE HIM A LIAR. ANDREAS: If we say that we have not sinned, we reject his word, which is spirit and life. CATENA.
ASKING FORGIVENESS. BEDE: God’s word says: “Surely there is not a righteous man on earth who does good and never sins.” He himself has taught us not only that we cannot escape sin but also that we should pray: “Forgive us our debts, as we forgive our debtors.”Therefore when we see even the apostles praying for their sins to be forgiven, as the Lord taught them, no one should think, as Pelagius taught, that it is possible to lead a sinless life here on earth.
