But he that lieth in deadly sin of pride or envy, or such other, he is so blinded by the devil, that for the time he hath no power of his free will, and therefore he cannot well withstand fleshly likings when they come, but falleth down willingly to them, as a beast doth to carrion; and inasmuch as he hath no general will before to God principally, because that he is in deadly sin, therefore the lust of gluttony into which he falleth easily, is to him deadly sin, for he maketh no resistance either general or special. (John Climacus)

I have argued that if our consumption is mindful - appreciating those who make what we consume and thanking God - it can be sacramental.

Climacus argues if our consumption is combined with pride or envy it can never be mindful. I agree. Pride and envy will distract us from true thanksgiving.

I especially agree if our consumption is motivated by pride and envy. When these are our motivation we do not so much see, hear, taste, smell, or feel as use consumption as a prop. In pride and envy we value what we consume only for how it flatters our self-image.
