Quote by Joseph Pohle
““When corruption (corruptio specierum) sets in, e. g. when the host becomes mouldy or the contents of the Chalice sour, Christ is no longer pres ent. The cessation of the Real Presence must not, how ever, be conceived as a " retransubstantiation," 27 for while Christ may be the terminus ad quern of a substan tial conversion, He can never become its terminus a quo.””
