But seeing that, however pure an eye one may have, i.e. with however single and sincere a heart one may live, he yet cannot look into the heart of another: whatever things could not have become apparent in deeds or words, are disclosed by trials. Now trial is twofold; either in the hope of obtaining some temporal advantage, or in the terror of losing it. And especially must we be on our guard, lest, when striving after wisdom, which can be found in Christ alone, in whom are hid all the treasures of wisdom and knowledge; ¹ --we must be on our guard, I say, lest, under the very name of Christ, we be deceived by heretics, or by any parties whatever defective in intelligence, and lovers of this world. For on this account He adds a warning, saying, "Not every one that saith unto Me, Lord, Lord, ² shall enter into the kingdom of heaven; but he that doeth the will of My Father which is in heaven, he shall enter into the kingdom of heaven:" lest we should think that the mere fact of one saying to our Lord, "Lord, Lord," belongs to those fruits; and from that he should seem to us to be a good tree. But those are the fruits, to do the will of the Father who is in heaven, in the doing of which He has condescended to exhibit Himself as an example.
