Dominus Vobiscum
I have read this:
catholic.com/quickquestions/why-can-only-priests-consecrate-the-eucharist
My question is more along the lines of why a priest with valid Apostolic Succession is needed to consecrate the host. Let me pose a not-so-hypothetical Protestant query, that I will roughly paraphrase below.
hanks!

From the OT:
- The Old Testament History: Kingdom of Priests
So it isn’t just the Church which is a kingdom of priests. Israel was a kingdom of priests, too. This came home to me in a very forceful way a few years ago when a history of Old Testament Israel was released by Baker Book House. The book is called, Kingdom of Priests, and the author is an Old Testament professor at Dallas Theological Seminary. So even mainstream Evangelicals, like the folks at Baker Book House and Dallas Theological Seminary, recognize that Israel was a kingdom of priests.
- Exodus 19:21-22: Ministerial priests
But that did not stop Israel from having a special, ministerial priesthood. In fact, if you keep reading in Exodus 19, when you get down to verse 21 & 22, you will find God telling Moses to warn the people and the priests not to come onto the holy mountain, lest the Lord break out against them. So even in the very same chapter God is calling the whole nation a kingdom of priests, there is still a separate, ministerial priesthood.
The NT:
- New Testament priesthood
a. The priestly duty of preaching
i. Rom 15:15-16
The Bible indicates New Testament priests offer at least two sacrifices. One of them is discussed in Romans 15:15-16. In the New International Version of this passage, we read:
“I have written you quite boldly on some points, as if to remind you of them again, because of the grace God gave me to be a minister of Christ Jesus to the Gentiles with the priestly duty of proclaiming the gospel of God, so that the Gentiles might become an offering acceptable to God, sanctified by the Holy Spirit.”
Paul tells us that because he has been given a calling as a professional minister of Christ, he has a priestly duty of preaching the gospel so that the Gentiles may be an offering—a sacrifice to God.
ii. Every elder in every church
This is not something only he has. Every elder in every church has that same “priestly duty” of preaching the gospel. So Paul here conceives of the office of the New Testament minister as a priestly office.
iii. Ministers as priests, not the congregation
Notice that the hearers of the gospel in this passage are not depicted as priests, but as the sacrifice to God. Paul draws a distinction between himself and his duty of preaching the gospel, and his readers and their duty of hearing it. It is the minister, not the congregation, who is here pictured as priest.
b. The Eucharist
i. The name of the sacrament
But converts to the faith are not the only sacrifice our New Testament elder-priests are to offer. They are also charged with distributing the sacraments, and one sacrament in particular has a sacrificial character: communion, or the Eucharist, as the Bible refers to it in the Greek text of Mark 14:23, Luke 22:19, and 1 Corinthians 11:24.
Also, read about Korah and his rebellion:
Most of us know those two examples, but who was Korah and what was his rebellion? The story is found in Numbers 16, and it concerns precisely the issue which is before us today: Whether the fact that all believers are priests means that there is no ministerial priesthood. Korah said it does mean that, and he gathered a rebellion against Moses and Aaron to usurp the priesthood from them. Numbers 16 says: “Now Korah . . . and Dathan and Abiram . . . took men; and they rose up before Moses, with a number of the people of Israel, two hundred and fifty leaders of the congregation, chosen from the assembly, well-known men; and they assembled themselves together against Moses and against Aaron, and said . . . ‘You have gone too far! For all the congregation are holy, every one of them, and the LORD is among them; why then do you exalt yourselves above the assembly of the LORD?’”
After this you can guess what happened. The men loaded up their censers and tried to offer incense before the Lord, but God caused the earth to open its mouth and swallow up Korah, Dathan, and Abiram, then he caused fire to come out of the Tabernacle and swallow up the two hundred and fifty men offering incense, showing that they were not to be priests, not the ones to offer incense, even though God had said that in one sense the whole congregation were priests.
It is against this sin that the book of Jude warns us, because the same thing can happen in the New Testament age. Don’t think you can confine the warning against Korah’s rebellion to the Old Testament age. Jude tells us it was going on in his day as well.
It is against this erroneous conclusion that the book of Jude warns us, proclaiming that people who fall into this error perish in the rebellion of Korah. In the New Testament age there were people rising up and assuming the priesthood who had not been authorized to do so, and Jude records their judgment for us.
