Today is the feast of St. Beda, also known as the Venerable Bede, Doctor of the Church.
The Pelagians were unwilling to believe that the whole mass of the human race was corrupted and condemned in one man. It is the grace of Christ alone that cures and frees from this corruption and condemnation. For why will the righteous be saved with difficulty? Is it a labor for God to set free the righteous? Far from it. But to show that [our] nature was rightly condemned the Omnipotent himself does not wish to set [us] free easily from so great an evil, because sins are easy to slip into and righteousness is strenuous, except for those who love; but charity, which makes them lovers, is of God.
[Bede, Commentary on the Seven Catholic Epistles, Cistercian Press (Kalamazoo, MI: 1985), p. 113.He is commenting on 1 Peter 4:18.]
