I feel like we are getting somewhere now, Guanophore. You rightly stated that there were bishops that taught heresy, who had received the episcopate via the laying on of hands extending back to the apostles. You also stated that the teachings of the apostles are preserved through the succession. Those are two contrary statements. How can the very people who teach heresy preserve the true teachings? The only thing you can do to reconcile this contradiction is to pick and choose particular secessions and claim them innocent of heresy. But at least we can agree that the succession itself has no bearing on the soundness of the doctrines they teach.
The other thing you provided was your biblical base for your opinion. You said,
If all authority comes from God, and Paul tells the bishop he installed to undertake these tasks “with all authority”, what other authority could it be?
I will tell you.
Exousia: power of choice, liberty of doing as one pleases.
Exousia is always translated as power or authority in the New Testament. The most relevant verse is 2Cor. 10:8.
“For even if I should boast somewhat more about our authority (
exousia), which the Lord gave for edification and not for your destruction, I shall not be ashamed.”
Exousia is the word Paul used to in reference to what the apostles received from Christ. However, that is not the word he used in reference to Titus’ authority; that word is
epitagē.
Epitagē: an injunction, mandate, command.
Epitagē is translated as “commandment” in six places in the New Testament (Rom. 16:26, 1Cor. 7:6 and 7:25, 2Cor. 8:8, 1Tim. 1:1, Tts. 1:3) and as authority in one place (Tit. 2:15).
“Speak these things, exhort, and rebuke with all authority (
epitagē). Let no one despise you.” (Tts. 2:15)
The authority Paul speaks of in Titus 15 is clearly not the same as he applied to himself as coming from Christ. Titus’ authority is really a commandment to teach, rebuke, etc. It is bound in the teachings of the apostles. His instruction from Paul is similar to that of Timothy’s: to teach, rebuke, and correct according to the Gospel they received and the Scriptures they learned.
“All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, and for instruction in righteousness.” (2Tim. 3:16)
“If anyone speaks, let him speak as the oracles of God. If anyone ministers, let him do it as with the ability which God supplies, that in all things God may be glorified through Jesus Christ, to whom belong the glory and the dominion forever and ever. Amen.” (1Pet. 4:11)
