There is only One who is Alpha and Omega and that is God Himself. Jesus clearly identifies Himself as that in 22:12-13. You deny that, yes, but that's another matter.
The fact, truth, and reality is that the great preponderance of biblical evidence is against the idea that Christ is an angel. As stated earlier -There are numerous other, more important, more clear Scripture references to show the truth that Jesus Christ is God come in the flesh, the Savior and not an angel. However, I believe it is glaringly obvious even to those who might only skim over this thread that your posts would much, MUCH rather avoid the more important and clear Scriptures - very much like an alley cat would avoid a full immersion bath. For me, this is nothing new - I have years of personal experiences similar to what's happening here. JWs simply do not have the capacity to honestly deal with the more important, straightforward and clear verses regarding the Deity of Christ like John 1:1; 1:18; 14:1; 14:8-9; Col. 1:15-16; 2:10; Heb. 1:3 and 8 (and there are more).
