Hmm…some Catholics are a bit anti-Islamic in this thread. That is baaaad.
But, as to the question of whether Jesus married and had children, I’m going to give an answer that will seem complex at first, but, if you think it over, it’ll become much clearer.
In regards to corporal marriage - that is, a man and a woman marrying each other - Jesus did not marry. He was born, lived, died, rose, and ascented into heaven a virgin. His virginity is a requirment, because He is God and Man. This is where the complex theology comes in.
In the Old Testament, God had made a Covenant with Isreal. This Covenant was always viewed by the Israelities as a marriage between a husband (God) and a wife (Israel). God used this marital image many times when He spoke to Israel: when He said He was a jealous God, He meant He demanded absolute allegience from Israel, just as a wife is with her husband; when He said Israel had committed adultery, He meant Israel had turned from God to false gods and idols; when He spoke to the prophets, He used very strong terms to describe His love for Israel, such as in the Song of Songs when He described Israel’s beautiful body.
Over time, Israel became more and more unfaithful, and God warned that if Israel did not return to Him, He would form a new people; but in the same breath He also stated He would never leave Israel and that in the end Israel would belong to Him again and forever. The Jews took this warning seriously; they believed that when the Messiah arrived, he would restore Israel to God, actualize the Covenant between God and Israel, and drive away all unfaithfulness from the people. This was the hope of Judaism.
God knew the Jews’ hope, and He decreed to make it real in a way far beyond Israel could ever imagine, thus showing her His unfathomable mercy. He took on human flesh, joining humanity to His Divinity, thus - in virtue of the union of God and mankind - fulfilling every hope of Judaism, ultimately in the actualization of the Covenant. In Jesus Christ, God and man had become totally united in marriage; the universalization of Israel, the actuality of her marriage to God, the coming of the Messiah, and the restoration of the Kingdom of Israel had been accomplished simply by God becoming incarnate, that is, assuming human flesh (otherwise known aa the Incarnation). But Jesus, as Man, was not simply a male human being, but was actually the totality of the whole human race, that is to say, as Man He was Adam, the new Adam, head of the human race and first man to be resurrected to glory (there is a difference between people being risen and people rising to glory, as is shown in the Old Testament; the Israelities knew the difference between a prophet bringing man back from the dead and God raising the dead to new life, to glory and eternal life). But Jesus, as Man, was not like Adam; the first Adam was born from dust, but Jesus came from heaven; the first Adam was only a man, but Jesus was a spiritual man, that is, He was a divinized man, God and man in union, and in light of this union His manhood was spiritualized, diviinized, glorified (i.e., resurrected to glory).
Now, as I’m sure you’re aware, every couple must have children. So if Jesus was the marriage of God and man, where were His children? The Christians were His children. Mary - or Marian as some like to call her - was the Mother of God. But Jesus made her more than this at the foot of the cross. He gave her to His disciples through the Apostle John, making her their Mother, the Mother of all believers and of all the living. Because of this, Mary became the new Eve (Eve means “mother of the living”). And just as Adam was married to Eve, so too the new Adam is married to the new Eve. However, their marriage is not corporal, but spiritual. If it was corporal, they would be guilty of incest. But this spiritual marital union began, in a way beyond our understanding, at the Incarnation, when Jesus was conceived in Mary’s womb, and the marriage was consummated on the Cross; just as sexual relations consummates a corporal marriage and begets life, so too the greatest means of unification of man and God and of restoring the divine life in souls, which man had lost because of original sin - Jesus’ death on the Cross - consummated the spiritual marriage. This is why Jesus’ death is called His hour of glory or “the wedding of the Lamb”, because on the cross He had taken the Church (of whom Mary is a figure and sign) in marriage and given Himself to her - just as a man gives himself to his wife in bed - and she had bore Him Christians - just as a woman bears her man children. And because of the death of Jesus, His followers - including His Mother Mary - were no longer Jews but were Christians, and He Himself was no longer a Jew but the Father of the Church. And Mary was the Mother of the Church, as His new Eve.
In conclusion, did Jesus marry and have children? Yes, in a spirutal way, a spiritual way which could only be possible if He is truly God and Man.
The answer I gave, though, I fear is not adequent. I apologize for this. If you have any questions, feel free to ask. I will be happy to answer them for you.
