How does someone unify a union?
So they don’t actually have union with each other unless they are having sex?
Now, a married couple that does not engage in the one flesh union is still married; if they are celibate for, perhaps, health reasons, then they are living in anticipation of the Real Thing, that is, True Union with the Bridegroom.
Again, it seems you are saying that a married couple without sex cannot consider themselves a union but can only anticipate when they will really have union, which is when the Bridegroom comes. Is that what you’re saying?
However, I will say that a marital couple that does not engage in the one flesh union is like a Christian who does not encounter Christ in the Eucharist.

There is no closer union possible this side of heaven and some people are missing out!
I believe there is no closer union possible than the indwelling of the Holy Spirit. After all, when Christ left, he said He would send the Comforter, the Holy Spirit, to be His presence with the disciples until He returns, and he will someday return as the Bridegroom. I have His presence with me in the person of the Holy Spirit, so I am not missing out on a thing.
Just wondering, Bookworm, will your church recognize the marriage of someone who’s been divorced and now is married to another?
Matthew 5:32 says “But I say to you that whoever divorces his wife for any reason
except sexual immorality causes her to commit adultery.” So Christ even included an immorality exemption in the divorce guidelines. So I believe that if someone is the innocent partner of an adulterous spouse, and that spouse leaves the marriage, then the innocent party is free to get remarried. Would the Catholic position be that the innocent party has committed an unpardonable sin if they get remarried?
