Despite its familiarity, 1 Corinthians 6:19a is a scriptural text that retains much of its capacity to surprise: “do you not know that your body is the temple of the Holy Spirit…?” The body isn’t just claimed for God’s ownership or service, but is presented as a site of his personal residence and of our communion with him.

The Möbius strip-like unity between self and body to which we can be awakened in sexual relations is the basis for the profoundly personal nuptial union. It is not accidental that Paul treats the profound power of bodily union to effect personal union in the verses that immediately precede 1 Corinthians 6:19. As Paul argues in verse 18, sexual relations, as they directly relate to the fundamental reality of our embodiment—of our being and not just having bodies—implicate the whole person in an especially profound manner. To sexually unite with someone is to be personally united to them in an enduring fashion. The body isn’t just aninstrument of sexual pleasure, but a means of self-donation, personal union and communion.
