Read it and weep....In this scene, Jesus's brothers who arrived with His Mother to speak with Him at Capernaum were two of His four cousins, Joseph and Simon of Alphaeus. Joseph and Simon had heard that Jesus had recently done carpentry work in Korazim for a widow whose husband had died, and they, particularly Joseph, was the most visually and vocally angry at Him for making money for her and her children, but not His own Mother, etc., and they were there to confront Him about it, but Jesus set them straight. I know some of those details not from any of the accounts of the Four Evangelists, as they are incomplete, but rather from The Gospel as Revealed to Me, or The Poem of the Man-God, a multi-volume book that's an expansion of the four Gospels of Christ by Jesus through His spokesperson, Maria Valtorta.
46 While he yet talked to the people, behold, his mother and his brethren stood without, desiring to speak with him.
47 Then one said unto him, Behold, thy mother and thy brethren stand without, desiring to speak with thee.
48 But he answered and said unto him that told him, Who is my mother? and who are my brethren?
Why didn't he speak to his family?
Right, he equated his disciples with his immediate family.
And all this time you thought he was shining on his disciples.
