Bede the Venerable
Catena Aurea · Markusevangelium 3
There came then his brethren and his mother, and, standing without, sent unto him, calling him. And the multitude sat about him, and they said unto him, Behold, thy mother and thy brethren without seek for thee. And he answered them, saying, Who is my mother, or my brethren? And he looked round about on them which sat about him, and said, Behold my mother and my brethren! For whosoever shall do the will of God, the same is my brother, and my sister, and mother.
(ubi sup.) But mystically, the mother and brother of Jesus means the synagogue, (from which according to the flesh He sprung,) and the Jewish people who, while the Saviour is teaching within, come to Him, and are not able to enter, because they cannot understand spiritual things. But the crowd eagerly enter, because when the Jews delayed, the Gentiles flocked to Christ; but His kindred, who stand without wishing to see the Lord, are the Jews who obstinately remained without, guarding the letter, and would rather compel the Lord to go forth to them to teach carnal things, than consent to enter in to learn spiritual things of Him. (Ambr in Luc. 6, 37.). If therefore not even His parents when standing without are acknowledged, how shall we be acknowledged, if we stand without? For the word is within and the light within.
