Thus the Lord God is said to have appeared as a common man to Abraham while he was seated by the oak of Mamre. But [Abraham] immediately fell down, although he saw a man with his eyes, and worshiped him as God, besought him as Lord and confessed that he was not ignorant as to who he was, using these very words, "O Lord, judge of all the earth, will you not judge righteously?" For if it should be unreasonable to suppose that the unbegotten and immutable substance of God the Almighty was changed into the form of man and, in turn, that the eyes of the beholders were deceived by the phantasm of something created and that such things were falsely invented by Scripture, who else could be proclaimed God and the Lord who judges all the earth and judges righteously, appearing in the shape of a man—if it be not proper to call him the first cause of all things—than his preexistent Word alone?

The holy Virgin knew that He was not the Son of Joseph, and yet calls her husband His father according to the belief of the Jews, who thought that He was conceived in the common way. Now to speak generally we may say, that the Holy Spirit honoured Joseph by the name of father, because he brought up the Child Jesus; but more technically, that it might not seem superfluous in St. Luke, bringing down the genealogy from David to Joseph. But why sought they Him sorrowing? Was it that he might have perished or been lost? It could not be. For what should cause them to dread the loss of Him whom they knew to be the Lord? But as whenever you read the Scriptures you search out their meaning with pains, not that you suppose them to have erred or to contain anything incorrect, but that the truth which they have inherent in them you are anxious to find out; so they sought Jesus, lest perchance leaving them he should have returned to heaven, thither to descend when He would. He then who seeks Jesus must go about it not carelessly and idly, as many seek Him who never find Him, but with labour and sorrow.

He is not found as soon as sought for, for Jesus was not among His kinsfolk and relations, among those who are joined to Him in the flesh, nor in the company of the multitude can He be found. Learn where those who seek Him find Him, not every where, but in the temple. And do thou then seek Jesus in the temple of God. Seek Him in the Church, and seek Him among the masters who are in the temple. For if thou wilt so seek Him, thou shalt find Him. They found Him not among His kinsfolk, for human relations could not comprehend the Son of God; not among His acquaintance, for He passes far beyond all human knowledge and understanding. Where then do they find Him? In the temple! If at any time thou seek the Son of God, seek Him first in the temple, thither go up, and verily shalt thou find Christ, the Word, and the Wisdom, (i. e. the Son of God.)

Because moreover He was the Son of God, He is found in the midst of the doctors, enlightening and instructing them. But because He was a little child, He is found among them not teaching but asking questions, as it is said, Sitting in the midst of the doctors, hearing them, and asking them questions. And this He did as a duty of reverence, that He might set us an example of the proper behaviour of children, though they be wise and learned, rather to hear their masters than teach them, and not to vaunt themselves with empty boasting. But He asked not that He might learn, but that asking He might instruct. For from the same source of learning is derived both the power of asking and answering wisely, as it follows, All who heard him were astonished at his wisdom.
