For whosoever shall do the will of my Father who is in heaven, the same is my brother, and sister, and mother.
All Commentaries on Matthew 12:50 Go To Matthew 12
Gregory The Dialogist
AD 604
If someone can become the brother of the Lord by coming to faith, we must ask how one can become also his mother. We must realize that the one who is Christ’s brother and sister by believing becomes his mother by preaching. It is as though one brings forth the Lord and infuses him in the hearts of one’s listeners. And that person becomes his mother if through one’s voice the love of the Lord is generated in the mind of his neighbor.
