The question is “CAN YOU SEE IT”
NAB
Matt 1:25 He had no relations with her until she bore a son, and he named him Jesus.
Footnote: 25 Until she bore a son: the evangelist is concerned to emphasize that Joseph was not responsible for the conception of Jesus. The Greek word translated “until” does not imply normal marital conduct after Jesus’ birth, nor does it exclude it.
Douay-Rheims Bible
Matt 1:25 And he knew her not till she brought forth her firstborn son: and he called his name JESUS
Footnote: 25 “Till she brought forth her firstborn son”… From these words Helvidius and other heretics most impiously inferred that the blessed Virgin Mary had other children besides Christ; but St. Jerome shews, by divers examples, that this expression of the Evangelist was a manner of speaking usual among the Hebrews, to denote by the word until, only what is done, without any regard to the future. Thus it is said, Genesis 8. 6 and 7, that Noe sent forth a raven, which went forth, and did not return till the waters were dried up on the earth. That is, did not return any more. Also Isaias 46. 4, God says: I am till you grow old. Who dare infer that God should then cease to be: Also in the first book of Machabees 5. 54, And they went up to mount Sion with joy and gladness, and offered holocausts, because not one of them was slain till they had returned in peace. That is, not one was slain before or after they had returned. God saith to his divine Son: Sit on my right hand till I make thy enemies thy footstool. Shall he sit no longer after his enemies are subdued? Yea and for all eternity. St. Jerome also proves by Scripture examples, that an only begotten son, was also called firstborn, or first begotten: because according to the law, the firstborn males were to be consecrated to God; Sanctify unto me, saith the Lord, every firstborn that openeth the womb among the children of Israel, etc. Ex. 13. 2.
Haydocks Catholic Bible Commentary
Ver. 25. See note on ver. 18. — St. Jerome assures us, that St. Joseph always preserved his virginal chastity. It is “of faith” that nothing contrary thereto ever took place with his chaste spouse, the blessed Virgin Mary. St. Joseph was given her by heaven to be the protector of her chastity, to secure her from calumnies in the birth of the Son of God, to assist her in her flight into Egypt, &c. &c. We cannot sufficiently admire the modest reserve of both parties. Mary does not venture to explain to her troubled husband the mystery of her pregnancy; and Joseph is afraid of mentioning his uneasiness and doubts, for fear of troubling her delicate mind and wounding her exquisite feelings. So great modesty, reserve and silence, are sure to be approved by heaven; and God sends an angel to Joseph in his sleep, to dissipate his doubts, and to expound to him the mystery of the incarnation. (Haydock)
Ver. 18. The account of the birth of Jesus Christ follows his genealogy. From these words, “before they came together,” Helvidius and others have started objections, which have been answered long ago by St. Jerome, where he shews in many examples from Scripture, that the words before and until do not signify what happened afterwards; for that point is left indefinite, but only what was done before, or not done. Thus when it is said, Sit thou at my right hand, till I make thine enemies thy footstool, Psalm cix, by no means signifies, that after the subjection of his enemies, the Son of God is no longer to sit at the right hand of his Father. In common conversation, when we say that a man died before he reached his 30th year, we do not mean that he afterwards attained it. Or, should we say that Helvidius died before he did penance, we cannot mean that he afterwards did penance: the same conclusion should be deduced from the words, “before they came together,” the end being accomplished by the power of the operation of the Holy Ghost, without their going together. If we should advance, that such a man was cured before he went to a physician, the natural inference would be, that he did not go to a physician at all. Thus also in the language of Scripture, the word first-begotten does not mean after whom others were born, but before whom no one was born, whether there were further issue or not. And the reason is, because the law required that a sacrifice should be offered for the first-born, and that he should be redeemed very soon after his birth; nor did it allow the parents to wait and see if any other son should be born. (Estius) — True and perfect marriage, and continual living in the same, without knowing each other. (St. Augustine, lib. ii. Consen. Evang. chap. i.) (Bristow)
