Hebrews 1 rules out future prophets because Jesus is the final revelation.
Hebrews 1
1God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets,
2Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;
3Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high
Jude 1:3 (King James Version)
Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints.
And, there was a change of priesthood and that priesthood can not be passed on to others it is non-transferable.
Hebrews 7
1This Melchizedek was king of Salem and priest of God Most High. He met Abraham returning from the defeat of the kings and blessed him, 2and Abraham gave him a tenth of everything. First, his name means “king of righteousness”; then also, “king of Salem” means “king of peace.” 3Without father or mother, without genealogy, without beginning of days or end of life, like the Son of God he remains a priest forever.
4Just think how great he was: Even the patriarch Abraham gave him a tenth of the plunder! 5Now the law requires the descendants of Levi who become priests to collect a tenth from the people—that is, their brothers—even though their brothers are descended from Abraham. 6This man, however, did not trace his descent from Levi, yet he collected a tenth from Abraham and blessed him who had the promises. 7And without doubt the lesser person is blessed by the greater. 8In the one case, the tenth is collected by men who die; but in the other case, by him who is declared to be living. 9One might even say that Levi, who collects the tenth, paid the tenth through Abraham, 10because when Melchizedek met Abraham, Levi was still in the body of his ancestor.
11If perfection could have been attained through the Levitical priesthood (for on the basis of it the law was given to the people), why was there still need for another priest to come—one in the order of Melchizedek, not in the order of Aaron? 12For when there is a change of the priesthood, there must also be a change of the law. 13He of whom these things are said belonged to a different tribe, and no one from that tribe has ever served at the altar. 14For it is clear that our Lord descended from Judah, and in regard to that tribe Moses said nothing about priests. 15And what we have said is even more clear if another priest like Melchizedek appears, 16one 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. 17For it is declared:
“You are a priest forever,
in the order of Melchizedek.”[a] ** 18The former regulation is set aside because it was weak and useless 19(for the law made nothing perfect), and a better hope is introduced, by which we draw near to God.
20And it was not without an oath! Others became priests without any oath, 21but he became a priest with an oath when God said to him:
"**The Lord has sworn
and will not change his mind:
‘You are a priest forever.’ " 22Because of this oath, Jesus has become the guarantee of a better covenant. **
23Now there have been many of those priests, since death prevented them from continuing in office; **24but because Jesus lives forever, he has a permanent priesthood. **25Therefore he is able to save completely[c] those who come to God through him, because he always lives to intercede for them.
26Such a high priest meets our need—one who is holy, blameless, pure, set apart from sinners, exalted above the heavens. 27Unlike the other high priests, he does not need to offer sacrifices day after day, first for his own sins, and then for the sins of the people. He sacrificed for their sins once for all when he offered himself. 28For the law appoints as high priests men who are weak; but the oath, which came after the law, appointed the Son, who has been made perfect forever.
