Catena Aurea · Lukasevangelium 2
And when he was twelve years old, they went up to Jerusalem after the custom of the feast. And when they had fulfilled the days, as they returned, the child Jesus tarried behind in Jerusalem; and Joseph and his mother knew not of it. But they, supposing him to have been in the company, went a day’s journey; and they sought him among their kinsfolk and acquaintance. And when they found him not, they turned back again to Jerusalem, seeking him. And it came to pass, that after three days they found him in the temple, sitting in the midst of the doctors, both hearing them, and asking them questions. And all that heard him were astonished at his understanding and answers. And when they saw him, they were amazed: and his mother said unto him, Son, why hast thou thus dealt with us? behold, thy father and I have sought thee sorrowing. And he said unto them, How is it that ye sought me? wist ye not that I must be about my Father’s business? And they understood. not the saying which he spake unto them.
(Metaphrastes vel Geometer.) The feast having been celebrated, while the rest returned, Jesus secretly tarried behind. As it follows, And when they had fulfilled the days, as they returned, the child Jesus tarried behind in Jerusalem; and his parents knew not of it. It is said, When the days were accomplished, because the feast lasted seven days. But the reason of His tarrying behind in secret was, that His parents might not be a hindrance to His carrying on the discussion with the lawyers; or perhaps to avoid appearing to despise his parents by not obeying their commands. He remains therefore secretly, that he might neither be kept away nor be disobedient.
