Over the centuries since The Bible was written, humans have, for a variety of reasons, usually well-meaning and honest, but sometimes not, applied their personal interpretation of their favorite parts of the Bible to their own time and circumstances, far removed from what is truly found in God's Word. Some even today see the ultimate fulfillment of Biblical Scriptures taking place, not coincidentally, where they themselves just happen to be. They deny what the Bible plainly says, and shape the Sacred Scriptures for their own self-accommodating purposes, using them as a means of glorifying or justifying themselves, rather than The Creator, by Whom, and for Whose purposes, they were written.
While allegorical interpretation does have correct and legitimate usage, its self-centered application is actually more ancient than Christianity, having originated with the pagan mystics, and then adopted by some Jewish and Christian philosophers. According to the Encyclopedia Britannica, 15th Edition:
"The allegorical method attempts to overcome the difficulties of morally perplexing Biblical passages and to harmonize them with certain traditions and accepted teachings of the synagogue or church. By assigning to each feature of a text a hidden, symbolic, or mystical meaning beyond the primary meaning that the words convey in their literal sense, the allegorical interpretation seeks to make the text more comprehensible, acceptable, and relevant to the present."
