Q,
I am sorry I did not get back to you right away. I had something to do with my kids. I looked thru your notes about the Levitical Priesthood and Melchizedek. I would like to make these few points. Sorry in advance if this is long, I will try to explain why I think your reasoning about the priesthood is flawed in as simple a way I can. I will focus mostly on Hebrews chapter 7, please get out your bible to follow along with this.
Melchizedek is mentioned the first time in Genesis chapter 14:17-20. Here he meets with Abraham and Abraham gives Melchizedek gifts. In the OT there were Kings and there was the Priesthood, but here in Genesis we have Melchizedek who is both King and Priest. Melchizedek is the "type" for Jesus Christ, who will be King and Priest for the people. That is why Jesus is called by the author of Hebrews the Priest in the "order of Melchizedek".
By Abraham giving gifts to Melchizedek, he was showing Melchizedeks superiority to himself. In Hebrews 7:8-10, it is showing that since the Tribe of Levi was "in" Abraham, The Levitical Priesthood was also acknowleging the superiority of Melchizedek. Therefore this is showing that Melchizedek's priesthood is greater than the one descending from Abraham. When the Messiah came, his Priesthood superceded the Levitical Priesthood.
Hebrews 7:11 shows that God never planned the Levitical Priesthood to be permanent. Nor does he plan to ever restore it. God, when our Messiah came, totally set aside the Old Testament way of his people approaching him. See also verses 12,18,19a
Hebrews 7:19,22 shows that thru Jesus, God has now provided us a better way to approach him. Jesus will never die and will never need to be replaced by anyone - verse 23.
verse 25 - Jesus will hold his priesthood permanently and is the only one that can save us completely.
verse 27 - Jesus sacrifice is better than any animal sacrifices. The animal sacrifices pointed to the need of a new better sacrifice and was set in place temporarily. But God knew this type of sacrifice could never wash away man's sin completely. But Jesus sacrifice can. And Jesus sacrifice only has to be given once for all time and not over and over like animal sacrifices had to.
God's new arrangement is for us to go thru his Son, our High Priest and we can approach him directly now. We can also approach him any time day or night, no matter where we are. This is the new, better way. There is no more need for the human priesthood.
I want to make one point about your using a verse in Matthew 22:
About Matthew 22 - the parable of the wedding banquet
this parable is about being invited into God's heavenly kingdom and not into a Priesthood. In verse 22:14 it says "many are called but few are chosen". this statement is talking about the natural Jews and how many were called to accept the invitation to the kingdom but refused because they would not accept Christ. Thus many of them were called or "invited" but few believed and were ultimately chosen. Again, this is not an invitation to a preisthood but invitation to the heavenly kingdom as heirs with Christ.
