John Calvin — Commentary on Scripture

Matthew 1:25

There have been certain folk who have wished to suggest that from this passage (Matt 1:25) that the Virgin Mary had other children than the Son of God, and that Joseph then dwelt with her later; but what folly this is! For the gospel writer did not wish to record what happened afterwards; he simply wished to make clear Joseph's obedience and to show also that Joseph had been well and truly assured that it was God who had sent His angel to Mary. He had therefore never dwelt with her nor had he shared her company... And besides this Our Lord Jesus Christ is called the first-born. This is not because there was a second or a third, but because the gospel writer is paying regard to the precedence. Scripture speaks thus of naming the first-born whether or not there was any question of the second. Thus we see the intention of the Holy Spirit. This is why to lend ourselves to foolish subtleties would be to abuse Holy Scripture.

Matthew 1:25

And knew her not. This passage afforded the pretext for great disturbances, which were introduced into the Church, at a former period, by Helvidius. The inference he drew from it was, that Mary remained a virgin no longer than till her first birth, and that afterwards she had other children by her husband. Jerome, on the other hand, earnestly and copiously defended Mary's perpetual virginity. Let us rest satisfied with this, that no just and well-grounded inference can be drawn from these words of the Evangelist, as to what took place after the birth of Christ. He is called first-born; but it is for the sole purpose of informing us that he was born of a virgin. It is said that Joseph knew her not till she had brought forth her first-born son: but this is limited to that very time. What took place afterwards, the historian does not inform us. Such is well known to have been the practice of inspired writers. Certainly, no man will ever raise a question on this subject, except from curiosity; and no man will obstinately keep up the argument, except from an extreme fondness for disputati…

Matthew 13:55

Under the word 'brethren' the Hebrews include all cousins and other relations, whatever may be the degree of affinity.

Matthew 13:55

Helvidius displayed excessive ignorance in concluding that Mary must have had many sons, because Christ's 'brothers' are sometimes mentioned.
