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.
