Who Is Jesus' True Family?

Matthew 12:46-50

As he was yet speaking to the multitudes, behold his mother and his brethren stood without, seeking to speak to him.

And one said unto him: Behold thy mother and thy brethren stand without, seeking thee.

But he answering him that told him, said: Who is my mother, and who are my brethren?

And stretching forth his hand towards his disciples, he said: Behold my mother and my brethren.

For whosoever shall do the will of my Father, that is in heaven, he is my brother, and sister, and mother.
