you guys are so clueless, you don't even realize you're the people Paul was talking about.The first church, its growth, doctrine, and practices, were recorded for us in the New Testament. Jesus, as well as His apostles, foretold that false teachers would arise, and indeed it is apparent from some of the New Testament epistles that these apostles had to fight against false teachers early on. Having a pedigree of apostolic succession or being able to trace a church's roots back to the "first church" is nowhere in Scripture given as a test for being the true church. What is given is repeated comparisons between what false teachers teach and what the first church taught, as recorded in Scripture. Whether a church is the "true church" or not is determined by comparing its teachings and practices to that of the New Testament church, as recorded in Scripture.
For instance, in Acts 20:17-38, the Apostle Paul has an opportunity to talk to the church leaders in the large city of Ephesus one last time face to face. In that passage, he tells them that false teachers will not only come among them but will come FROM them (vv. 29-30). Paul does not set forth the teaching that they were to follow the "first" organized church as a safeguard for the truth. Rather, he commits them to the safekeeping of "God and to the word of His grace" (v. 32). Thus, truth could be determined by depending upon God and "the word of His grace" (i.e., Scripture, see John 10:35).
The Catholic and Orthodox teachings don't change. Yours changes from generation to generation.
You are preaching a false gospel and no one can say anything because you created a fantasy of Sola Scripture. This false teaching opened the door to thousands of more false teachings.
