And the LORD said unto him, Who hath made man's mouth? or who maketh the dumb, or deaf, or the seeing, or the blind? have not I the LORD? Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say.
And he said, O my Lord, send, I pray thee, by the hand [of him whom] thou wilt send.
And the anger of the LORD was kindled against Moses, and he said, [Is] not Aaron the Levite thy brother? I know that he can speak well. And also, behold, he cometh forth to meet thee: and when he seeth thee, he will be glad in his heart. And thou shalt speak unto him, and put words in his mouth: and I will be with thy mouth, and with his mouth, and will teach you what ye shall do. And he shall be thy spokesman unto the people: and he shall be, [even] he shall be to thee instead of a mouth, and thou shalt be to him instead of God. – Exodus 4:10-16
As a man, Christ’s lineage was Judah, not Aaron. More importantly, Christ is God. He is divine.
Melchizedek was not a mortal priest either and his priesthood preceded the Levitical priesthood.
The priesthood of Christ is unchangeable and endless.
For the priesthood being changed, there is made of necessity a change also of the law. For he of whom these things are spoken pertaineth to another tribe, of which no man gave attendance at the altar. For [it is] evident that our Lord sprang out of Juda; of which tribe Moses spake nothing concerning priesthood.
And it is yet far more evident: for that after the similitude of Melchisedec there ariseth another priest, Who is made, not after the law of a carnal commandment, but after the power of an endless life. For he testifieth, Thou [art] a priest for ever after the order of Melchisedec.
For there is verily a disannulling of the commandment going before for the weakness and unprofitableness thereof. For the law made nothing perfect, but the bringing in of a better hope [did]; by the which we draw nigh unto God.
And inasmuch as not without an oath [he was made priest]: (For those priests were made without an oath; but this with an oath by him that said unto him, The Lord sware and will not repent, Thou [art] a priest for ever after the order of Melchisedec:)
By so much was Jesus made a surety of a better testament. And they truly were many priests, because they were not suffered to continue by reason of death: But this [man], because he continueth ever, hath an unchangeable priesthood.
Wherefore he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them. For such an high priest became us, [who is] holy, harmless, undefiled, separate from sinners, and made higher than the heavens; Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people's: for this he did once, when he offered up himself.
For the law maketh men high priests which have infirmity; but the word of the oath, which was since the law, [maketh] the Son, who is consecrated for evermore. – Hebrews 7:11-28
Amen! Very deep and appropriate Scriptures for this conversation. Thank you.
Amen, amen and amen.
Indeed, as we read in Hebrews especially, the Priesthood of Christ is not levitical and therefore Catholic priesthood is likewise in the order of Melchizedek. Theologically, there is but one Catholic priest, Jesus Christ, because there is but one Mass, the Golgotha hill.
This one was not founded on the Law of Moses, but predated the Law

This is another reason why purely linguistic dictionary-based analysis ("ιερευς" means "priest" so therefore!? "πρεσβυτερος" must mean something other than "priest") is flawed. There are many kinds of priests in the Bible.
