You don't understand Greek? Alpha and Omega are the first and last letters of the Greek alphabet. The first and last is an obvious reference to Alpha and Omega as used in the same chapter.
Ummm, how does that demonstrate that I don't understand Greek? Because I disagree with you? First and Last is not the same as Alpha and Omega, even if Alpha and Omega are the first and last letters, the context is not the same even if there is a similarity in terms of letters. Alpha and Omega is a specific title that only the Father uses, Yashua does not use it in Verse 1:11 (despite the KJV's inclusion of what doesn't appear in early manuscripts.)
Can you guess why the KJV decided to include Alpha and Omega in Verse 1:11? There's a reason why the two are said separately. You are the one who clearly doesn't understand the Greek. The concept of Alpha and Omega may be "First and last Letter", but they are not the same concept. Can you find a single link that says that "First and Last" and "Alpha and Omega' are the same thing, despite Alpha and Omega being the first and last letters? What is the "First and Last" supposed to mean to begin with?
As I've asked several times to many posters to no avail,
what does "Last Adam" mean? All your argument is is an attempt to brush aside the fact that "Firstborn of Creation" and "Last Adam" would thoroughly make Yashua the "First and the Last", especially if he is the "Firstborn of the dead". Thus, "Alpha and Omega" is a very specific kind of "First and Last" which is exclusive to the Father, while the actual "First and Last" is a reference that is not exclusive to the Father.
Otherwise, it would be redundant to say "Alpha and Omega, first and the last".
