For whosoever shall do the will of my Father which is in heaven, the same (he, Revised Version; αὐτός: Matthew 1:21, note) is my brother, and sister, and mother. He is fall; he sums up in himself all such relations. Observe that our Lord does not raise the question whether or not his mother and brethren now believed on him. He is only speaking of the claims of relationship as such. From Mark 3:21, however (which seems to refer to the same occasion), we may conclude that the motive for this endeavour to interrupt him lay in unbelief. If so, Mary was either unaware of this or had herself been over-persuaded into momentary impatience (John 2:3) and distrust. If the latter alternative be adopted, she forms a parallel to the Baptist (Matthew 11:3, note).
