I'm sure this isn't what you mean by "ruling out forgeries".
Gospel of Thomas, etc...those books.
Whether these churches comprised the RCC or not is irrelevant to the discussion.
No, it really isn't irrelevant, because you go on to say:
You are free to choose your O.T. canon from the Council of Jamnia which rejected the deuterocanonical books as well as all of the writings of the disciples of Jesus, or from the canon of one of the early Christian Councils, or you can even make up your own.
That IS your point. The RCC canon is the only "true canon." Just as the RCC is the only "true and visible church."
The central problem is that you take the word "church" to mean a denomination, or one body of believers. I take it to mean ALL believers, of ALL denominations, who know the Truth. We may disagree on some unclear things in the Bible, but on the "basics" we all agree, and are brothers/sisters.
You will notice that in the Jerusalem Council not one of the leaders said, "OK, we need to be all on the same page here. So, gentiles now must be Jews first, then baptized as Christians." Neither did they say, "Jews, the Torah is obsolete. From now on no more circumcision, kashrut, etc." There was room for DIFFERENCES, yet ONE BODY.
The Gospel is the important message that we need to be on the same page with one another...the rest is under
Phil. 2:12:
"work out your own salvation with fear and trembling." To be obedient to the Holy Spirit as He leads YOU, personally, without condemnation of others who aren't YOU, and have a different path to walk in the LORD, because even though united, we are still individuals with different gifts and different ministries, etc.
Together perfection.
