Psalm 109.
"The Lord said to my Lord: Sit thou at my right hand: Until I make thy enemies thy footstool."
Father is speaking to Christ. And he says that:
"4 The Lord hath sworn, and he will not repent: Thou art a priest for ever according to the order of Melchisedech."
Father is speaking to Christ that he is priest in order of Melchizedek. Thus Christ is not Melchizedek. He could not be.
As for Hebrews:
Ver. 3. Without father, &c. Not that he had no father, &c. but that neither his father, nor his pedigree, nor his birth, nor his death, are set down in Scripture. (Challoner) — Not that he was without father and mother, says St. Jerome, (ep. cxxxvi.) for Christ himself was not without a Father according to his divinity, nor without a Mother in his humanity; but because his genealogy is not given in Genesis, as that of the other patriarchs is, but he is abruptly introduced without any mention of either his birth or death. In Melchisedech all was prophetical and figurative of Jesus Christ; and Abraham undoubtedly in this patriarch saw Jesus Christ in spirit, and exulted that all the nations of the earth were to be blessed in him. Abraham, your father, greatly desired, says our Lord to the Jews, to see the day of my coming: he saw it, and was filled with joy. (John viii. 56.)
And of course "but made like unto the Son of God" alone is sufficent to say that Melchisedek is not Christ for he was made like unto Christ.
