In us it is not only the spirit which ought to be sanctified, but also our behaviour, manner of life, and our body. What does the apostle Paul mean when he says that the wife is sanctified by the husband and the husband by the wife? And what is the meaning of the Lord's words to those who asked concerning divorce whether it is lawful to put away one's wife as Moses commanded? "Because of the hardness of your hearts," he says, "Moses wrote this; but have you not read that God said to the first man, You two shall be one flesh? Therefore he who divorces his wife except for fornication makes her an adulteress." But "after the resurrection," he says, "they neither marry nor are given in marriage."
"For a woman is bound, as long as her husband is alive." As a consequence, therefore, the husband is also bound, as long as his wife is alive. This bond renders any further union impossible without the implication of adultery. Hence, four adulterers are produced of necessity from the two marriages, if the wife remarries and the husband marries an adulteress. However, a more infamous adultery is imputed to the one who remarries after the dismissal of his wife for other than the cause of fornication. Matthew spoke of this type of adultery. Such a one is not the only one who commits adultery, but, as we read in Mark: "Whoever puts away his wife and marries another, commits adultery against her; and if the wife puts away her husband, and marries another, she commits adultery."
God created marriage. As the union is from God, so divorce is from the devil. But one is allowed to divorce a wife in case of fornication for the precise reason that one never originally wished to have a wife who has not preserved conjugal fidelity to her husband.
(ubi sup.) In Matthew it is more fully expressed, Whosoever shall put away his wife, except it be for fornication. (Matt. 19:9.) The only carnal cause then is fornication; the only spiritual cause is the fear of God, that a man should put away his wife to enter into religiono, as we read that many have done. But there is no cause allowed by the law of God for marrying another, during the lifetime of her who is quitted.
The Lord answered them: whoever divorces his wife and marries another commits adultery with this second wife; likewise a wife who has left her husband and joined with another becomes an adulteress.
(Vict. Ant. e Cat. in Marc.) The Lord calls by the name of adultery cohabitation with her who is not a man's wife; she is not, however, a wife, whom a man has taken to him, after quitting his first; and for this reason he commits adultery upon her, that is, upon the second, whom he brings in. And the same thing is true in the case of the woman; wherefore it goes on, And if a woman shall put away her husband, and marry another, she committeth adultery; for she cannot be joined to another as her own husband, if she leave him who is really her own husband. The law indeed forbade what was plainly adultery; but the Saviour forbids this, which was neither plain, nor known to all, though it was contrary to nature.
(non occ.) For a repetition of a saying of the Word, produces not weariness, but thirst and hunger; (Ecclus. 24:29) wherefore it is said, They that eat me shall yet be hungry, and they that drink me shall yet be thirsty; for the tasting of the honied words of wisdom yields all manner of savour to them who love her. Wherefore the Lord instructs His disciples over again; for it goes on, And he saith unto them, Whosoever shall put away his wife and marry another, committeth adultery upon her.
"After all," said Clare, "they had a right to happiness." We were discussing something that once happened in our own neighbourhood. Mr A. had deserted Mrs A. and got his divorce in order to marry Mrs B., who had likewise got her divorce in order to marry Mr A. And there was certainly no doubt that Mr A. and Mrs B. were very much in love with one another. If they continued to be in love, and if nothing went wrong with their health or their income, they might reasonably expect to be very happy.
It was equally clear that they were not happy with their old partners. Mrs B. had adored her husband at the outset. But then he got smashed up in the war. It was thought he had lost his virility, and it was known that he had lost his job. Life with him was no longer what Mrs B. had bargained for. Poor Mrs A., too. She had lost her looks — and all her liveliness. It might be true, as some said, that she consumed herself by bearing his children and nursing him through the long illness that overshadowed their earlier married life.
You mustn't, by the way, imagine that A. was the sort of man who nonchalantly threw a wife away like the peel of an orange he'd sucked dry. Her suicide was a terrible shock to him. We all knew this, for he told us so himself. "But what could I do?" he said. "A man has a right to happiness. I had to take my one chance when it came."
[...] Everyone (except Mr A. and Mrs B.) knows that Mr A. in a year or so may have the same reason for deserting his new wife as for deserting his old. He will feel again that all is at stake. He will see himself again as the great lover, and his pity for himself will exclude all pity for the woman.
