It has been said before that “______”s (insert whatever Christian denomination you wish to pick on) are against pre-marital sex because it might lead to dancing… :)
But on a more serious note, the topic of ‘pre-marital sex’ (a.k.a. ‘sex before marriage’) is an interesting one. Many Christians can assume that there is a specific verse in the Bible forbidding it…
There is no such verse.
But really, there is no such thing (as we shall see) as pre-marital sex, either…
As always, how one defines something is always important. As far as the Bible is concerned, ‘marriage’ has absolutely nothing to do with ceremonies and signing papers (let alone expensive receptions, etc.), and everything to do with two becoming one (see Genesis 2:24).
This ‘one-ness’ shows up in all areas of a marriage relationship – financial one-ness, emotional one-ness and –the one relating to our topic here– physical one-ness.
Sex is the most intimate form of physical interaction that two people can share. When two people share their physical bodies with one another – they spiritually become one. (If you want biological correlates for the reality of this spiritual bonding that takes place – you can look up how the brain releases oxytocin during intercourse.)
People who sexually share their bodies are ‘married’ – whether or not they’ve been through a ceremony or put ink to paper. The ceremony of putting person to person is the ceremony that binds them together.
The point –if it’s not already obvious– is that because the very act of sex binds people together, then ‘sex before marriage’ is a practical (not to mention logical) contradiction.
