I would like to be better informed of the difference in the priesthood of all the faithfull and the priesthood of the ordained ministers. Im speaking about Catholic faith, of course.
There are many books on the subject. It you're theologically inclined, one that you might want to consider is Yves Congar’s Lay People in the Church or Pope John Paul II's Christifidelis Laici.
One of the things that I found interesting, early on, is that there is a common distinction in the New Testament that's not immediately obvious in English.
In passages regarding ordained ministers of Christ's sacraments, such as James 5:14, the term most commonly used is some form of presbyteros (elder).
In passages regarding the priesthood of the faithful, such as 1 Peter 2:9 and Revelation 1:6, the term most commonly used is some form of hiereus (sacred, one who offers sacrifice, belonging to the temple).
The latter is also the term most commonly used for priests of older covenants, as in Matthew 2:4 (chief priests = arch-hiereis).
The reason this distinction is not obvious in English is that we use one word, "priest," for all of these, even though the English word "priest" is derived only from the first, presbyteros.
One of the things this suggests to me is that the faithful have a priesthood somewhat analogous to the priests of previous covenants (the hiereus). They offered sacrifice to God, and so do we: "I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship."
But the priesthood of the ordained ministers of Christ's sacraments (the presbyteroi), the Eucharist especially, appears to be something beyond this, something new, for the service and edification of God's kingdom of priests. We offer to God what is ours, what has been given to us, while they offer to God for our benefit what is uniquely Christ's: Christ's own sacrifice.
A lot of this seems similar to your own thinking.
This is just some of my own thinking, mind you. You should definitely look to the teaching of the Church and to better theologians than I. :)
