Were you to be correct, you would have to demonstrate a clear discontinuity between the first century meaning of 'episkopos' and its present meaning. Ask any Orthodox Christian and s/he will assure you there is no such discontinuity. A cursory glance at church history would confirm that.
I'm quite happy with the Bible as a primary historical source and have never said I'm not so I'm not quite sure what the relevance of the above is. However, the NT is a first century document and the Cathars existed from the 11th to 14th centuries and I'm asking you for primary source documents from that era
The problem is Matt: that if you deny that the Cathars existed as Bible believing Christians, as others claim that they do; and continue to support the idea of the RCC as the bearer of the gospel throughout all ages, then you have a corrupt organization that doesn't have a clue what the gospel is as the bearer of God's good news to man as God's messenger. This organization has destroyed the Bible (see Wycliffe), persecuted believers (the Albigenese), massacred them (especially under Innocent III), and have the blood of thousands of believers on their hands. Their torture of Christians through various Inquistions is more horrible than Hitler's treatment of the Jews in the holocaust. And yet you claim that they are the ones that have preserved the message of God's Word faithfully throughout the centuries. This theory is absurd. The Orthodox Church is no better. Their message of salvation is no different than that of the Catholic Church.
Now we can look at history from two different ways, and both involve the Bible as our primary source. First we must define the word "bishop" to see what we are speaking about.
The KJV says:
1 Timothy 3:1 This is a true saying, If a man desire the office of a bishop, he desireth a good work.
Now the WEB (World English Bible) :
1 Timothy 3:1 This is a faithful saying: if a man seeks the office of an overseer he desires a good work.
A couple of others:
1 Timothy 3:1 Stedfast is the word: If any one the oversight doth long for, a right work he desireth; (Young's)
1 Timothy 3:1 The word is faithful: if any one aspires to exercise oversight, he desires a good work. (Darby)
--Notice in the last two translations (Young's and Darby's), the word "office" is not even present, nor is it present in the Greek. The word "overseer" is a better and more accurate translation, especially considering all the religious/political baggage that the word "bishop" carries with it.
--The current term "bishop" as defined by denominational organizations such as Orthodox and the RCC never existed in NT times. There was no hierarchial organization in the first century. One cannot find such a concept in the Bible.
Take a look at Acts 20:17,28
Acts 20:17 And from Miletus he sent to Ephesus, and called the
elders of the church.
Acts 20:28 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.
--Note that elders, overseers (episkopos or bishop), "feed the flock" (work of the shepherd) or "pastor" are all descriptive of the same office, the same position, the same man, just different aspects of his ministry.
Now one can look at history from two ways: from the present to the first century, or from the first century to the twentieth.
Going back in history, we as independent Baptists, simply pattern our churches after the churches in the NT. Above is the description of the office of a bishop or pastor. More information of the polity of the local church is given in the pastoral epistles, and yet more on its doctrine in the rest of the epistles. We have models in the book of Acts, as Paul went on three different missionary journeys, establishing about one hundred local churches, but never a denomination. There is no such thing as a denomination in the NT. All of these churches were independent one of another. There was no pope. No bishops in the modern sense of the word, no priests, etc. There was no hierarchies in the NT.
We pattern our churches after the NT. We believe the Bible to be our final source of authority in all matters of faith and practice (not tradition or any other source). Having so said, we also believe that there are and have been others that have beleived the same throughout all generations since the apostles that also have patterened their churches after the NT. This goes contrary to the RCC and Orthodox. It leaves at least 1500 years of history with no churches at all. This is an amazing and absurd claim to make. Independent Biblical churches did not just suddenly pop out of the air some time around the Reformation period. This is an absurd claim. They existed throughout all ages ever since the Apostolic Age.
Now working from the NT to our present day.
Acts 14:21-23 And when they had preached the gospel to that city, and had taught many, they returned again to Lystra, and to Iconium, and Antioch,
22 Confirming the souls of the disciples, and exhorting them to continue in the faith, and that we must through much tribulation enter into the kingdom of God.
23 And
when they had ordained them elders in every church, and had prayed with fasting, they commended them to the Lord, on whom they believed.
Note where these churches were located: Derbe, Lystra, Iconium, Antioch.
These towns were not exactly close to each other for the common person of that time. Communication wasn't common or easy. The churches were independent of each other. That is why Paul went to a place like Corinth and spent a year and a half there--time to establish the church so that it could operate on its own before he left.
Here there is no trace of the RCC or the Orthodox, or even any hint of such an organization like theirs. Neither can their doctrines be substantiated from the Bible. It is the Bible that is our authority, not tradition. The Bible is our source material here. Start here and then trace the history of these churches up to our time, if possibe. Try to connect them to the RCC or Orthodox. It can't be done. The sources that Agnus gave are not credible nor are the RCC. Both of them contradict each other. The RCC's claim that Peter was pope at Rome for 25 years is absurd, impossible, and defies all historical evidence. Claims made by either the Orthodox or the RCC are simply claims and nothing more.
The RCC did not originate until the fourth century with the advent of Constantine, and the Orthodox was well after that.
