Melchizedek can't be a being with no beginning. He can be one with no end as even us in Christ according to the Lord's own word will never die.
I have no problem with you believing in the orthodox version of the trinity. I am not in the least offended by the trinity. My Jesus is all that the Father is but has always been the Son and He and His Father are one.
This was also written about Melchizedek. I would state he was a mortal man.
This man, however, did not trace his descent from Levi, yet he collected a tenth from Abraham and blessed him who had the promises.
About Jesus
For it is clear that our Lord descended from Judah, and in regard to that tribe Moses said nothing about priests.
So without genealogy and stating Jesus's genealogy is the same writings suggest the priesthood wasn't based on genealogy, Father or Mother and a beginning of a priesthood starting with a ancestor.
Yet this was shown
one who has become a priest not on the basis of a regulation as to his ancestry but on the basis of the power of an indestructible life.
The writer has to be in error as Melchizedek can't be a being with no beginning. And Jesus can't be Melchizedek as there would be no need to appoint Him a 2nd time.
Well, there you have it. You don't believe what is written.
(Heb. 7:3) "Without father, without mother, without descent, having neither beginning of days, nor end of life; but made like unto the Son of God; abideth a priest continually."
Clear declaration of the eternality of God the Son, and thus also God the Father and Holy Spirit.
