Finally, hear Paul as he speaks boldly, and mark how clearly he discovers these: “Beware of evil workers, beware of the concision. Beware lest any man spoil you through philosophy and vain deceit. See that you walk circumspectly, because the days are evil.” In fine then, what man shall have any excuse who hears these things in the Church from prophets and apostles, and from the Lord Himself, and yet will give no heed to the care of his soul, and to the time of the consummation, and to that approaching hour when we shall have to stand at the judgment-seat of Christ?
