A reader brings the following quote to my attention, though warning that it
is an English translation of a French author citing a German letter:
“Joachim of Fiore is more ‘living’ or ‘alive’ to the modern mind than is St
Augustine.”—Letter of Jurgen Moltmann to Karl Barth, quoted in Henri de
Lubac, La Posterite spirituelle de Joachim de Flore, 2 vol. (Paris:
Editions Lethielleux, 1979-1981) 1:7.
