Still mayest thou see more in this image, though it be dark, namely, sensual love to thyself, in gluttony, sloth and lechery. These fleshly likings make a man full beastly, and far from the inward savour of the love of God and from the clear sight of spiritual things. But thou wilt say that thou must needs eat and drink and sleep, which thou canst not do without liking, therefore thou thinkest this liking is no sin. (John Climacus)

As Climacus continues consideration of the deadly sins we move from pride and envy to three closely related behaviors.

Gluttony: Excessive or voracious consumption.

Sloth: Constant disinclination to exertion; indolence, laziness, slowness.

Lechery: Carnality, lust, sexual promiscuity.

These are each a form of extreme self-indulgence, where a natural good is transformed into an unnatural craving.
