A major mistake?! That is absurd, as is the premise of a lack of difference between the dreams of Mohammed and the Dreams of John.
For the contrasts are multiple:
1. John vs. Muhammad. John is the apostle of love, mentioning it over 70 times in the gospel of John and 1 John and Revelation combined, in contrast to the Qur'an, where it is hardly mentioned if at all. 2. The Christ of John and Revelation, who is "the almighty," (Rv. 1:8) whom all creation will worship along with the Father. (Rv. 5:13-14) Who was dead; and, behold, is alive for evermore, (Revelation 1:18) who "wast slain, and hast redeemed us to God by thy blood out of every kindred, and tongue, and people, and nation;" (Revelation 5:9) who "loved us, and washed us from our sins in his own blood" (Revelation 1:5)
In stark contrast to the christ of the madman Muhammad, who reduced Christ to being a mere exalted perfect man, who did not die for our sins and rise, and who is not to be worshiped.
3. The mean of warfare John and Revelation: While Revelation 13:10) warns, "He that leadeth into captivity shall go into captivity: he that killeth with the sword must be killed with the sword. Here is the patience and the faith of the saints," (Revelation 13:10) which is consistent with, J"My kingdom is not of this world: if my kingdom were of this world, then would my servants fight, that I should not be delivered to the Jews: but now is my kingdom not from hence;". (John 18:36) The only warfare of the saints for the kingdom of God will be supernatural. (Revelation 19:14,15)
In stark contrast Muhammad the mad-man engaged in physical bloodly warfare and captivity as the head of a physical theocracy, and his postMedinic exhorts religious violence.
Need i go on?
Well; considering that our FR Catholic friends insist that the 'church' has been CATHOLIC from Day One; John's writings SHOW how screwed up THEIR CHURCH has been since Day; oh; THREE or so!
Seven 'catholic churches' mentioned; ALL teaching EXACTLY what the Apostles taught !!
