Hygiene
The umbrella collects two Pauline references that treat the body as a moral and ascetic concern. Both stand in 1 Corinthians and turn on a single principle: what a person does with the body matters because the body itself is at stake.
Sin Lodged in the Body
The first text places sexual sin in a category of its own. Other sins are spoken of as outside the body, but sexual sin is a sin against one's own body: "Stop being a whore. Every sin that a man does is outside the body; but he who goes whoring sins against his own body" (1Co 6:18). The verse is the umbrella's clearest claim that personal conduct and bodily integrity cannot be separated.
Self-Control and the Trained Body
The second text uses athletic training as a figure for disciplined living. The athlete's regimen is total — "every man who strives in the games exercises self-control in all things" — and is set against the perishable reward of the games and the imperishable reward of those who train for something more: "Now they [do it] to receive a corruptible crown; but we an incorruptible" (1Co 9:25). Bodily restraint is not the goal but the means; it is the form discipleship takes when it reaches the body.
