(18) The prophecy put forth in Revelation is complete. Dire penalties await those who add or subtract words that would change the meaning of any passage. Like the rest of the Bible, one can not choose to accept one part of Revelation and ignore the rest. It comes as a whole piece and must be accepted or rejected as a whole. This does not mean we have to understand everything about it, but we have to accept by faith that everything will become clear as the events come to take place.
(19) No true Christian would change the meaning of passages of this book (or by extension, the other books of the Bible). Thus, if someone intentionally rewords or interprets Scripture in a way that clearly violates the intent of the author (or God), it is likely that he is not a Christian, even if he claims to be one. There are parts of Scripture that can be interpreted in several ways. In other parts, the meaning of words, places, and phrases has been lost. In these cases, the interpreter must be very careful with how he might interpret a passage. However, if he keeps in mind the spirit and context of the entire Bible (and his relationship with God), he is more likely to make an accurate and useful interpretation of the obscure passage.
