Last year I spent a fair bit of time thinking and writing about sex, mostly in the context of the Sexual Detox booklet I was writing at the time. As I did so, I found myself beginning to think of sex within marriage as an interesting kind of parallel with Lord's Supper. Now, before you accuse me of blasphemy, know that I am not equating the two; rather, I am simply drawing out some similarities between them. What I mean to say is, I think it can be helpful to understand sex as a kind of "marriage sacrament."
