“Now, if these were Mary’s sons, instead of children that Joseph had during a previous marriage, then, at the moment of the passion Mary never would have been given to the apostle John as his mother, when the Lord, addressing the two of them, said, ‘Woman, behold your son” , and to John, “Behold your mother” (John 19:26-27). For the Lord, to help her face her solitude, left her, in his disciple, the love of a son.Hilary of Poitiers , In Matthaeum I, 4; PL 9, 922.
