Imitation of Christ

Certa tanquam miles bonus; et si interdum ex fragilitate corruis, resume vires fortiores prioribus, confidens de ampliori gratia mea, et multum præcave a vana complacentia et superbia. Propter hoc multi in errorem ducuntur, et in cecitatem pæne incurabilem quandoque labuntur. Sit tibi in cautelam et perpetuam humilitatem ruina hæc superborum et de se stulte præsumentium.

Strive like a good soldier; and if sometimes you fail through weakness, put on your strength more bravely than before, trusting in My more abundant grace, and beware of vain confidence and pride. Because of it many are led into error, and sometimes fall into blindness well-nigh irremediable. Let this ruin of the proud, who foolishly lift themselves up, be to you a warning and a continual exhortation to humility.

Imitation of Christ, III, 6:5
