Revelation 1:5 KJV
And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood,
The claim is Michael was Jesus for the sake of living and dying, and then returned to being Michael, however, in the Revelation, which we are specifically commanded not to add to or take away from, the Faithful Witness declares He is Jesus. Not Michael.
So who will you believe?
Much love!
