By Dr. Donald DeMarco, Catholic Exchange - People look forward to the summer when being lazy becomes respectable. Or they may prefer the term, “indolent,” which seems to raise laziness to a higher level. Nonetheless, no one is proud of being lazy. ... St. Thomas Aquinas treated laziness under the term acedia. It is “sorrow over . . . an internal and divine good [in us]” (ST II-II, q. 35, a, 2). It is, for Aquinas, a sin against charity since it fails to accept “friendship with God” and “the spiritual life that dwells within us.” The Angelic Doctor in this instance is referring to spiritual laziness, the most pernicious kind.
