Sorry, Revelations makes my head hurt(as it should everyones), I havent completely digested it myself, nor probably never will. I take notes however, whenever I read it or build on them. I think it important to understand it as a portion for our times and understand it in relation to false prophets(generic Protestants included) who would use our not understanding it to deceive us. I recommend "Trial, Tribulation & Triumph: Before,During and After AntiChrist" by Desmond Birch. Highly acclaimed and recommended catholic work. This is the best book I have on Catholic eschatology amongst about 5 on my shelf.
