Jesus Defines His True Family

Mark 3:31-35

And his mother and his brethren came; and standing without, sent unto him, calling him.

And the multitude sat about him; and they say to him: Behold thy mother and thy brethren without seek for thee.

And answering them, he said: Who is my mother and my brethren?

And looking round about on them who sat about him, he saith: Behold my mother and my brethren.

For whosoever shall do the will of God, he is my brother, and my sister, and mother.
