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.
(Ambr in Luc. 6, 36. Bede ubi sup.) Being asked therefore by a message to go out, He declines, not as though He refused the dutiful service of His mother, but to shew that He owes more to His Father’s mysteries than to His mother’s feelings. Nor does He rudely despise His brothers, but, preferring His spiritual work to fleshly relationship, He teaches us that religion is the bond of the heart rather than that of the body. Wherefore it goes on, And looking round about on them which sat about him, he said, Behold my mother and my brethren.
