A Brief Commentary on the Apocalypse is a classic religious text by Sylvester Bliss that deals with the subjectsof bible interpretation and and bible criticism and revelation. This great old book features this passage:

"The Apocalypse should be regarded as a peculiarly interesting portion of scripture: a blessing being promised those who read, hear, and keep the things which are written therein. It has been subjected to so many contradictory interpretations, that any attempt to comprehend its meaning is often regarded with distrust, and the impression has become very prevalent, that it is a "sealed book, "--that its meaning is so hidden in unintelligible symbols, that very little can be known respecting it, and that to attempt to unfold its meaning, is to tread presumptuously on forbidden ground.
