The greek was very explicit..
The catholic church has redefined it to meet their needs..But God knows the difference between an elder and a priest because He was the one to outline the roles in the OT, and the one to choose the specific roles for the NT church
the greek word for elder is different than the greek words for priest.. archiereus which translates into "High Priest" and hiereus which translates one that OFFERS SACRIFICES.
The role of the priesthood in scripture was to offer sacrifices.. That is what a priest does in scripture.. God set aside one tribe to be priests, they were not granted any land as God was their inheritance .
The greek have a couple words for priest
hiereus
1) a priest, one who offers sacrifices and in general in busied with sacred rites
a) referring to priests of Gentiles or the Jews,
2) metaph. of Christians, because, purified by the blood of Christ and brought into close intercourse with God, they devote their life to him alone and to Christ
and archiereus
Outline of Biblical Usage
1) chief priest, high priest
2) the high priests, these comprise in addition to one holding the high priestly office, both those who had previously discharged it and although disposed, continued to have great power in the State, as well as the members of the families from which high priest were created, provided that they had much influence in public affairs.
3) Used of Christ because by undergoing a bloody death he offered himself as an expiatory sacrifice to God, and has entered into the heavenly sanctuary where he continually intercedes on our behalf.
Neither role is given in scripture for the new church ..
Christ fulfilled the role of Priest on the cross.. there is no more sacrifice for sin
He is now our High Priest..
The word for elder is presbyteros here is the GREEK definition
1) elder, of age,
a) the elder of two people
b) advanced in life, an elder, a senior
1) forefathers
2) a term of rank or office
a) among the Jews
1) members of the great council or Sanhedrin (because in early times the rulers of the people, judges, etc., were selected from elderly men)
2) of those who in separate cities managed public affairs and administered justice
b) among the Christians, those who presided over the assemblies (or churches) The NT uses the term bishop, elders, and presbyters interchangeably
c) the twenty four members of the heavenly Sanhedrin or court seated on thrones around the throne of God
Now the Holy Spirit knows the difference in the greek words.. there is no priesthood provided for in the NT church.
There was no priests in the new church.it was about 300 AD before the first priesthood appeared..
I am not arguing over how best to translate “presbyteros”. I have simply pointed out that in the scripture, “presbyteros” is subject to apostolic succession and that the apostle’s task was to consecrate the Eucharist, that is, be priests.
The Hebrew levitical priesthood was indeed inherited, but this is why it is separate form the Catholic priesthood.
