The Instructions of Commodianus 46To Catechumens.

XLVI.--To Catechumens. In few words, I admonish all believers in Christ, who have forsaken idols, for your salvation. In the first times, if in any way thou fallest into error, still, when entreated, do thou leave all things for Christ; and since thou hast known God, be a recruit good and approved, and let virgin modesty dwell with thee in purity. Let the mind be watchful for good things. Beware that thou fall not into former sins. In baptism the coarse dress of thy birth is washed. For if any sinful catechumen is marked with punishment, let him live in the signs of Christianity, although not without loss. The whole of the matter for thee is this, Do thou ever shun great sins.
