“ Eusebius Amort, in 1735, admits the gravest differences of opinion; and the Bishop of Newport writes (p. 163) “to receive an Indulgence of a year, for example, is to have remitted to one so much temporal punishment as was represented by a year’s canonical penance. If you ask me to define the amount more accurately, I say that it cannot be done. No one knows how severe or how long a Purgatory was, or is, implied in a hundred days of canonical penance.” The rapid extension of these time-Indulgences is one of the most remarkable facts in the history of the subject. ”
