Nothing there shows Merriam Webster is wrong. I had assumed from the beginning this would be the tact you were going to take. It is a false approach.
The NT is Greek, not Hebrew. Different words are used for the Church leadership than are used in the Hebrew OT: overseers (episcopoi) and elders (presbyteroi), deacons (diakonoi). Essentially in the NT the High Priest is Jesus Christ (Heb. 3:1), the ministerial priests are Christ’s ordained ministers of the gospel (Rom. 15:16), and the universal priests are the entire Christian people (1 Peter. 2:5, 9).
Romans 15:16 English Standard Version (ESV)
16 to be a minister of Christ Jesus to the Gentiles in the ******priestly service of the gospel of God,******* so that the offering of the Gentiles may be acceptable, sanctified by the Holy Spirit.
