This is the only question I have for the OP. It concerns the section of canon law concerning “Separation with the Bond Remaining.”
Can. 1152 §1. Although it is earnestly recommended that a spouse, moved by Christian charity and concerned for the good of the family, not refuse forgiveness to an adulterous partner and not disrupt conjugal life, nevertheless, if the spouse did not condone the fault of the other expressly or tacitly, the spouse has the right to sever conjugal living unless the spouse consented to the adultery, gave cause for it, or also committed adultery.
§2. Tacit condonation exists if the innocent spouse has had marital relations voluntarily with the other spouse after having become certain of the adultery. It is presumed, moreover, if the spouse observed conjugal living for six months and did not make recourse to the ecclesiastical or civil authority.
§3. If the innocent spouse has severed conjugal living voluntarily, the spouse is to introduce a cause for separation within six months to the competent ecclesiastical authority which, after having investigated all the circumstances, is to consider carefully whether the innocent spouse can be moved to forgive the fault and not to prolong the separation permanently.
…
**Can. 1154 **After the separation of the spouses has taken place, the adequate support and education of the children must always be suitably provided.
**Can. 1155 **The innocent spouse laudably can readmit the other spouse to conjugal life; in this case the innocent spouse renounces the right to separate.
Here is my question: What is he going to do if his wife is unfaithful and sincerely repents? Will the habit of thought he is now entertaining force him to do what he has a right to do instead of what he might be more laudable for having done? Those who marry as virgins fall less often than those who had less self-mastery prior to marriage, but virgins-at-marriage do fall into adultery from time to time, too. It happens. What is he planning to do if that happens in his marriage?
According to the Church, if he were innocent he would have a right to separate, provided he was willing to suitably provide for the adequate support of his children. A civil court might not award custody to him, though. Since the Church would “earnestly recommended that a spouse, moved by Christian charity and concerned for the good of the family, not refuse forgiveness to an adulterous partner and not disrupt conjugal life,” is he willing to do the work to put aside any feelings of “repulsion” for the sake of his marriage and his children? Would he be willing to “laudably readmit the other spouse to conjugal life,” and renounce his right to separate with the bond remaining? Or is he going to choose to live without a wife until the wife of the valid marriage he left dies? Does he have a plan for that?
The man who can’t see himself getting beyond a failure in chastity by a woman who has repented and been chaste for years might have a lot of trouble with this one. That is also his right, but there is such a thing as being dead right, too. Even if he does marry a virgin, as is also his right, he would do better if he can at least envision doing the “laudable” thing, if it comes to that. He may have to, someday, and if he cannot, it may be his children who suffer for it.
That is worth thinking about, and if that is really the point BlueEyedLady is trying to make, I have to side with her. Sometimes what you have the right to do isn’t the best you can do.
