Wow, I agree with 99.9 percent of what you said but since this is said to be a bashing frenzy I will have to disagree with the statement below.
Never differentiated between bishops and elders,>>>>>>>
I believe the elders were basically the ones who were aged or had been long with the Christian knowledge.
Titus 1
5 For this cause left I thee in Crete, that thou shouldest set in order the things that are wanting, and ordain elders in every city, as I had appointed thee:
6 If any be blameless, the husband of one wife, having faithful children not accused of riot or unruly.
7 For a bishop must be blameless, as the steward of God; not selfwilled, not soon angry, not given to wine, no striker, not given to filthy lucre;
Timothy 3
1 This is a true saying, If a man desire the office of a bishop, he desireth a good work.
2 A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behavior, given to hospitality, apt to teach;
12 Let the deacons be the husbands of one wife, ruling their children and their own houses well.
Both Timothy and Titus were to pick elders and to appoint them to the position of Bishops and deacons.
What i mean by"never differentiated between bishops and elders" was that of referring to two ordained pastoral offices, which i think you concur with me on. And that there was no class of clergy distinctively titled "hiereus"="priest."
I believe the elders were basically the ones who were aged or had been long with the Christian knowledge.
There is no disagreement there, as Titus was to ordain mature qualified men, presbuteros (senior/elder), but he was to ordain such as elders in the formal sense, who are also called episkopos (superintendent/overseer).
Both Timothy and Titus were to pick elders and to appoint them to the position of Bishops and deacons.
Rather, the text you cited, Titus 1:5-7, uses presbuteros (senior/elder) and episkopos (superintendent/overseer) interchangeably, instructing pastor Titus to appoint presbuteros and thus telling him what the qualifications of a episkopos were to be.
Presbuteros likely is used to refer to the character of the person as a mature person, while episkopos refers to his function.
Also see,
And from Miletus he sent to Ephesus, and called the elders of the church. (Acts 20:17)
Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood. (Acts 20:28)
