Matthew 12:50

“For whosoever shall do the will of my Father, etc.] This is not to be understood of a perfect obedience to the will of God, revealed in his righteous law; for since this cannot be performed by any mere man, no one could be in such a spiritual relation to Christ: but of the obedience of faith to the will of God, revealed in the Gospel; which is to believe in Christ, and have everlasting life; (see <430640>John 6:40). This is the will of Christ’s Father, which is in heaven, and which is good news from heaven, to sinners on earth; and which Christ came down from heaven to do, and to declare to the children of men: such as “hear the word of God and do it”, as Luke says, (<420821>Luke 8:21) that…”

“See also Mark 3:31-35; Luke 8:19-21. His brethren - There has been some difference of opinion about the persons who are referred to here, some supposing that they were children of Mary his mother, others that they were the children of Mary, the wife of Cleophas or Alpheus, his “cousins,” and called “brethren” according to the customs of the Jews. The natural and obvious meaning is, however, that they were the children of Mary his mother. See also Mark 6:3. To this opinion, moreover, there can be no valid objection. Matthew 12:48 Who is my mother? ... - There was no want of affection or respect in Jesus toward his mother, as is proved by his whole life. See especially Luke 2:51, and John…”
