Now the birth of Jesus Christ happened this way: When his mother Mary was espoused to Joseph, before they came together, she was found to be with child of the Holy Spirit.
All Commentaries on Matthew 1:18 Go To Matthew 1
John Chrysostom
AD 407
Do not speculate beyond the text. Do not require of it something more than what it simply says. Do not ask, “But precisely how was it that the Spirit accomplished this in a virgin?” For even when nature is at work, it is impossible fully to explain the manner of the formation of the person. How then, when the Spirit is accomplishing miracles, shall we be able to express their precise causes? Lest you should weary the writer or disturb him by continually probing beyond what he says, he has indicated who it was that produced the miracle. He then withdraws from further comment. “I know nothing more,” he in effect says, “but that what was done was the work of the Holy Spirit.” Shame on those who attempt to pry into the miracle of generation from on high! For this birth can by no means be explained, yet it has witnesses beyond number and has been proclaimed from ancient times as a real birth handled with human hands. What kind of extreme madness afflicts those who busy themselves by curiously prying into the unutterable generation? For neither Gabriel nor Matthew was able to say anything more, but only that the generation was from the Spirit. But how from the Spirit? In what manner? Neither Gabriel nor Matthew has explained, nor is it possible. Do not imagine that you have untangled the mystery merely by hearing that this is the work of the Spirit. For we remain ignorant of many things, even while learning of them. So how could the infinite One reside in a womb? How could he that contains all be carried as yet unborn by a woman? How could the Virgin bear and continue to be a virgin? Explain to me how the Spirit designed the temple of his body. The Gospel of Matthew, Homily
