Brother: A Fraternal Epithet, Especially Among Christians--Instituted by Christ

For whoever does the will of My Father in heaven is My brother and sister and mother.”

And the King will reply, ‘Truly I tell you, whatever you did for one of the least of these brothers of Mine, you did for Me.’

For both the One who sanctifies and those who are sanctified are of the same family. So Jesus is not ashamed to call them brothers.

He says: “I will proclaim Your name to My brothers; I will sing Your praises in the assembly.”
