Neither you, however, nor our old friends, the ancient saints from the
origin of the world, could be purified otherwise than through the shedding of
my blood, “the bath of regeneration” [Ti 3.5], namely of the blood and water
flowing from my side [Jn 19.34]. (Rupert of Deutz, Commentary on the Song of Songs,
Fourth Book [trans. Jieon Kim and Vittorio Hösle; The Fathers of the
Church Medieval Continuation 22 [Washington, D.C.: The Catholic University of
America Press, 2024], )
