"Here we are informed that this beast upon which the woman rides, is full of names of blasphemy. It is not one name but many names, for the beast is filled with them. This word "blasphemy" requires special translation, or decoding. It was a familiar word in the New Testament era. It is not used so much today, but it does have its modern counterpart. Why did the Jews of Jesus' day call Him a blasphemer? That was always their charge against Him! It was because He dared to call God His Father and to call Himself the Son of God. Therefore, they called Him a blasphemer because He was not teaching and operating according to the rules and regulations which they had set down -- His doctrine was not that of the scribes and Pharisees, but He said that He spoke only what He heard personally from His Father. His entire message and ministry was outside of the "box" constructed by the religious leaders of the Jews. Today if a lawyer is not operating according to the rules laid down by the Bar Association he is called non-ethical or a malpractitioner. Just so, if a physician is not following the rules of treatment laid down by the Medical Association, he is labeled a malpractitioner. This gives you our modern counterpart of the ancient term blasphemy."

"Thus we can see that this beast upon which the woman rides symbolizes malpractice, that is, he appropriates to himself what belongs to God; he dishonors Him, vilifies Him, shamelessly offends all that is true and godly -- blasphemes Him. That is what both the world and religion do -- they usurp the place of God in men's lives, putting their authority above God's truth, dominating men's lives through malpractice! They are not doing things God's way! It is not the Father Himself speaking and acting through them. Rather, it is the elevation of Self to either impress, influence, coerce, or control men. You see this plainly in nearly all the rulers of the world's systems, and if you refuse their domination you will be persecuted, discriminated against, fined, imprisoned, exiled, or excommunicated! Oh, yes!"
