Direct biblical statement
Luke 8:19–21
The family of the Word
19 And his mother and brethren came unto him: and they could not come at him for the crowd.
20 And it was told him: Thy mother and thy brethren stand without, desiring to see thee.
21 Who answering, said to them: My mother and my brethren are they who hear the word of God and do it.

Why this matters
Jesus identifies his family by hearing and doing God’s word. The passage mentions his mother but makes discipleship the central criterion; it should not be reduced to an unqualified Marian compliment.
