Ross Douthat said this quote

In this America, too, the Christian teaching that every human soul is unique and precious has been stressed, by the prophets of self-fulfillment and gurus of self-love, at the expense of the equally important teaching that every human soul is fatally corrupted by original sin. Absent the latter emphasis, religion becomes a license for egotism and selfishness, easily employed to justify what used to be considered deadly sins. The result is a society where pride becomes 'healthy self-esteem', vanity becomes 'self-improvement', adultery becomes 'following your heart', greed and gluttony become 'living the American dream'.

~ Ross Douthat

The physical vanity of the diet-and-exercise obsessive is recast as the pursuit of a kind of ritual purity, hedged about with taboos and guilt trips and mysticized by yoga.
