Then it would probably be best to search the for material teaching against premarital sex, rather than cohabitation-take it from an extreme skeptic, the arguments in that arena are much more persuasive.
Actually, the argument against cohabitation takes in the pre-marital sex issues, but is not limited to them. The
intimacy of sex, its
unitive dimension draws much of its power from the totality of the shared reality of daily life in all of its other facets. There is a reciprocity between the unitive activities in bed and those in the rest of the house.
The key word here is
INTEGRITY.
Cohabitation, by engaging sex and shared living outside of the marriage covenant trains people in **DISINTEGRATION **of marital functionality and dignity. It does this by learning how to wrest the fruits of commitment from the tree without having to make the commitment. This assault leads to the ultimate denigration of the couple and their faith in the denigration of the very institution God created to serve as the prefigurement of the life of the Trinity and the Marriage of Jesus and His Church. Both are characterized by radically complete reciprocal self-donation. That doesn’t happen without a covenantal commitment. The arrangement becomes a farcical mime, a counterfeit.
The whole talk of cohabitation, absent this theological reality, misses the mark. There is a purpose for sex, for cohabiting, for sharing life and its joys and sorrows, within the context of marriage. Marriage is the crucible where the impurities of character are burned away as we refine our love. By definition, love requires commitment. It’s no small wonder, then, that cohabitation and marriage that rejects God’s wise design become the crucibles that consume the couple, rather than their impurities.
