CLV(i)
20 For if, while fleeing from the defilements of the world by the recognition of our Lord and Saviour Jesus Christ, yet, being again involved in these, they are being discomfited, their last state has become worse than the first."
21 For it were better for them not to have recognized the way of righteousness, than, recognizing it, to go back to what was behind, from the holy precept given over to them."
22 Now that in the true proverb has befallen them: "A cur turning to its own vomit,and "A bathed sow to her wallowing in the mire."
