Apostolic succession is taught in Scripture. Who do you think appointed the overseers (= bishops). The Apostles did!
But more to the point, one of the most vehement defenders of Apostolic succession was Irenaeus of Lyons, who was a disciple of Polycarp, who was a disciple of John, who was a disciple of Jesus. So three generations (and about 150 years) removed from the "beloved disciple" reclining on Jesus' breast, the true message had already been lost? And you think you've recovered it 2000 years later?
Doubtful, friend. Doubtful.
The word bishop, which you like used is translater elder in many cases. These men were not appointed by the apostles. That is unless you consider Timothy and Titus to be apostles. Peter calls himself an elder and an apostle. (I Peter 5:1) Do a little more Bible research and then get back to me.
