Some are, I think, "called" to priesthood. I suspect we all know some - they are the gurus of goodness who are spiritual healers. Many are not "ontologically elevated" or otherwise ordained; though many are.
That is one side of the coin, I think.
I have often wondered why, if the "sacramental presence" of Christ was as a "person" however mystical why some sacraments require "ordination" and others not. Are some "functions" of the "mystical body" more related to "bodily" and others "cerebral" or whatever?  Is not Church: one, holy, apostolic also?
I cannot speak for Mr. Tammeus' community, but I have a strong feeling that "ontological" elevation of our Catholic priests is as much of a ruse as is the exclusion of women from "ordination". 
It is really, I believe, a political/institutional ideology to rationalize and preserve oligarchy.  Of course, "ministers of sacrament" require formation, education, ratification and accountability for/to the body
