If a priest offers sacrifices - and that certainly was their role in Judaism - then the Christian has no need for priests, for we have no sacrifice to offer. Jesus did it himself, once for all.
Being ordained a deacon doesn’t mean you offer sacrifices. Being ordained an Elder does not either. That is where my objection to the word ‘priest’ comes from.
That is why the NT knows nothing of Christian priests, except in 1 Peter, where all believers are said to be “a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ.”
No sacrifice for forgiveness of sin, since there was only one, and it was past and not to be again.
It is also true that every baptized Christian is priest, prophet and king in his family, as St. Peter teaches. The word he used, by the way, "ιερατευμα " is not of the same root as "presbyteros".
