"The problem with MTD, in both its progressive and its conservative versions, is that it’s mostly about improving one’s self-esteem and subjective happiness and getting along well with others. It has little to do with the Christianity of Scripture and tradition, which teaches repentance, self-sacrificial love, and purity of heart, and commends suffering—the Way of the Cross—as the pathway to God. Though superficially Christian, MTD is the natural religion of a culture that worships the Self and material comfort."
