Bede : All iniquity is sin, etc. Such is the diversity of sins, he says, that everything which deviates from the rule of equity is counted among the sins, although small sins cannot in any way take away or diminish the merit of righteousness from the just, as long as they are those without which this life cannot be lived, and likewise there are certain sins so discordant with all justice, committed with such iniquity, that without any contradiction, unless they are corrected, they lead their perpetrator to eternal punishment. Concerning which it is written: The soul that sins shall die (Ezekiel 18). Blessed John's statement clearly repudiates the inept argument of the Stoics, who dared to say against all human sense and to affirm that all sins are equal, saying it makes no difference whether a man steals a human being, an ox, or a chicken, because it is not the animal but the intention that constitutes the crime. Jovinian the heretic followed them, asserting that there is no distinction between marriage and virginity, claiming that those who abstain in no way should be preferred in any privilege of recompense over those who simply partake in feasting. Therefore, everything that is unjustly committed or thought is to be referred to as sin. But there are some sins unto death, about which the Apostle says: For those who do such things shall not inherit the kingdom of God (Galatians 5). — Commentary on the Catholic Epistles
