Nope, keep reading, especially what Jesus did in the upper room.
Really? Then why does Hebrews 13:10 say "We have an altar from which those who serve the [Jewish] tabernacle have no right to eat" [NASB]?
An altar is a table for sacrifice, by definition. Clearly the sacrifice is something we Christians eat. Evangelicals and fundamentalists have to explain this away as figurative language, where "altar" means "cross" and "eat" means "believe in". It isn't figurative at all. It's absolutely literal.
Jesus Christ is ... the only mediator between us and God (1 Timothy 2:5).
Except that 1 Tm 2:5 doesn't actually say that in the inspired Greek text, and that interpretation is completely at odds with 1 Tm 2:1-4, which commands intercessory prayer (a form of mediation) by all Christians on behalf of everyone. The Greek has a word for "one and exactly one", monos, which is not the word translated "one" in 1 Tm 2:5. Look it up.
The New Testament teaches that there are to be elders (1 Timothy 3:1-7; Titus 1:6-9), deacons (1 Timothy 3:8-13), and pastors (Ephesians 4:11) – but not priests.
The Greek word for "elder", presbyter, is where we get the English word "priest". "Elder" and "priest" are the same office. And you forgot about overseers (1 Tm 3:1-7). The Greek word for "overseer," episkopos, is where we get words like "bishop" and "episcopal" and "episcopacy".
You should worry less about our "meaningless" traditions, and more about your shallow and sloppy exegesis.
Have you ever read the New Testament books?
1 Peter 2:9 But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light;
Rev 1:6 And hath made us kings and priests unto God and his Father; to him be glory and dominion for ever and ever. Amen.
furthermore the English word priest is derived from priester (Old English) which derives from Lative Presbyter (Elder)
And this is IN the bible
The English word “priest” is derived from the Greek word presbuteros, which is commonly rendered into Bible English as “elder” or “presbyter.” The ministry of Catholic priests is that of the presbyters mentioned in the New Testament (Acts 15:6, 23). The Bible says little about the duties of presbyters, but it does reveal they functioned in a priestly capacity.
They were ordained by the laying on of hands (1 Tm 4:14, 5:22), they preached and taught the flock (1 Tm 5:17), and they administered sacraments (Jas 5:13-15). These are the essential functions of the priestly office, so wherever the various forms of presbuteros appear–except, of course, in instances which pertain to the Jewish elders (Mt 21:23, Acts 4:23)–the word may rightly be translated as “priest” instead of “elder” or “presbyter.”
In Acts 20:17-38 the same men are called presbyteroi (v. 17) and episcopoi (v. 28). Presbuteroi is used in a technical sense to identify their office of ordained leadership. Episcopoi is used in a non-technical sense to describe the type of ministry they exercised. This is how the Revised Standard Version renders the verses: “And from Miletus he [Paul] . . . called for the elders [presbuteroi]of the church. And when they came to him, he said to them . . . ‘Take heed to yourselves and all the flock, in which the Holy Spirit has made you guardians [episcopoi], to feed the church of the Lord.'”
