I have turned back the clock to June 2016 to find a post at the blog of canonist Ed Peters, who also – to our benefit – comments on these electronic pages.
Peters breaks it down Barney style so that even the most obtuse of libs can follow.
Let’s be clear: marriage is marriage but cohabitation (as that word is nearly universally understood in social discourse) is only cohabitation. Where to begin?
Everybody starts off single. One stays single unless one goes through a ceremony called a wedding, at which point, one is (presumptively, at least) married. People who are married get to do certain things that people who are not married don’t get to do, like, say, submit a married-filing-jointly tax return with a certain someone and have sex with that same certain someone if they both so choose. In addition, though, married couples who are baptized get something else at their wedding, they receive a sacrament called Matrimony, and with that sacrament come very powerful graces put there by Jesus to help Christian couples living the difficult and wonderful thing called marriage.
But, if one is not married, one does not get to submit a married-filing-jointly tax return with anyone and one does not get to have sex with a certain no-one or with anyone else. Moreover, even if one is baptized (and regardless of what other sacramental or actual graces might be wonderfully at work in one’s life) a single person does not get the specific graces of Matrimony. Why? Because cohabitation is NOT marriage, let alone is it “true marriage”, and cohabiting couples do NOT share in the graces of Matrimony.
