Weighing in at a gargantuan 261 pages, Amoris Laetitia (“The Joy of Love”) is, by my quick reckoning, the longest such document in the history of the papal magisterium, and by a good 10 percent or more. Its sheer size suggests the wisdom — although probably the futility, too — of Pope Francis’s plea that his apostolic exhortation “on love in the family” be read “patiently and carefully,” piece by piece, and then pondered as a whole. The futility comes from the fact that various pre-exhortation Catholic spin machines have set a context for the reception of Amoris Laetitia that the world media will find irresistible, by focusing almost exclusive attention on the question of whether the pope would endorse one or other of Walter Cardinal Kasper’s proposals for admitting divorced and civilly remarried Catholics to holy communion (quick preview: Francis doesn’t). So look in the early going for a vast, global argument over whether a “door has been opened” or a “first step taken” to vindicating Kasper. Those who will say that Kasper has not been vindicated seem to me to have the better of the argument, on a close reading of the text of the exhortation. But that won’t prevent others, including German-speaking bishops and theologians who don’t seem capable of recognizing that their proposals were rejected by two synods of bishops, from claiming victory.
