Origen
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.
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.)
