Actually, you didn’t address it at all. To begin with, there was dispute in the earliest years of the Church as to what writings were valid and which were not. Many of the writings you accept were NOT universally accepted; which proves that they are NOT self-validating. This problem was not resolved within the early Church by the collective communities eventually coming to an informal consensus on which of the disputed writings were truly Scripture, it was solved by a formal council attended by bishops (overseer’s, as you pointed out) and submitted to the bishop of Rome for approval.
You say that the Jews handed down the scriptures of the Old Testament, which is true, but you completely fail to mention the disputes regarding which Jewish writings were accepted. This dispute existed within the Jewish community in the early days of the Church and they settled the question (for themselves, anyway) in a council held over 50 years after the death of Christ. However, no Christian at that time continued to view the Jewish religious leaders as still having the authority to determine what constitutes Scripture because that authority had been passed on the the Church of Christ’s New Covenant. Therefore, it is up to that Church to determine what the canon of BOTH the Old and the New Testaments.
You claimed that you declare the writings you accept as Scripture on your own authority. Well, I don’t accept you as an authority and you clearly have not demonstrated that you can be relied upon as one.
You have also claimed that extra-biblical writings are not doctrinally authoritative. I assume that you do so on your own authority again because there is no place in Scripture that says that only Scripture is authoritative; and certainly no place that prophecies your arrival for us.
What the extra-biblical writings of the early Church do show (regardless of whether or not they are doctrinally authoritative) is what the early Church - the Church led by the Apostles and by their immediate successors - actually believed and you clearly do not believe what they did.
Have you never found it interesting that, in
all of the creeds formulated by the early Church, a belief in the Church was included
but not a belief in Scripture? This is important because it shows that, while the writings of the early Church clearly show that they believed in the authority of Scripture, they also believed in an authoritative Church. Is this because belief in the Scripture was so self-evident that it need not be mentioned? No, otherwise there would be no mention of belief in God - certainly a self-evident belief among the early Christians
and included in every one of the creeds.
No, the only Church that holds to all that is taught in Scripture is the Catholic Church. The only Church that belives all of what the early Church taught is the Catholic Church. That is because the Catholic Church is the same Church as was the early Church. It is the same Church which was origianlly headed by the Apostles of Christ and which Christ Himself founded.
