ACC ~ 1 John 5 v17

MINOR INFRACTIONS VERSUS SINS LEADING TO DEATH. BEDE: The variety of sins is such that everything which fails to agree with the law of fairness is a sin, although minor infractions of the kind which are almost impossible to avoid in this life can be forgiven the righteous without too much difficulty. But there are other sins which are so contrary to any kind of righteousness that they will lead the one who does them into eternal punishment without any doubt whatsoever, unless he happens to put them right. ON 1 JOHN.

SINS THAT LEAD TO DEATH. OECUMENIUS: Only those sins which are not repented of lead to death. Judas, for example, although he showed remorse, did not repent and was led off to his death. But whoever has given himself over to Christ cannot commit mortal sin, even though his nature remains unchanged and he still sins. COMMENTARY ON 1 JOHN.
