In the present work (which first appeared in 1972), Adrienne von Speyr comments on selected verses from the biblical book that both the Fathers and the Rabbis considered to be the key to Scripture as a whole: the Song of Songs. The central theme of Adrienne’s commentary is eros, understood as an image of the incarnate, crucified agape in which God creates his Bride, the Church and weds her to himself. Following the tradition, Adrienne sees this spousal covenant of love as the hermeneutical key to all the mysteries of faith, to dogma, and to the proper use of speculative theology.
