But I have seen no evidence that the dominant roman church, in conjunction with the eastern church it was in communion with at the time, had the continuance of their beliefs and the eradication of contrary views in mind when they assmebled the accepted scriptures and declared other writings as heretical.
"At the time" there was only one catholic (universal) church. The eastern and western split took a long time and was to do with interpretation and power. However, I'm glad to see that you don't know of any "evidence" that the Christian church based the canon on "continuance" of its own beliefs and the eradication of contrary views. Evidently we agree on that.
True heresy consists of introducing ideas contrary to the Christian faith as written in the canon. Thus Mormonism is heresy; Christian Science is heresy and so on. These are not 'interpretations' but outright rejection of Christ and his teachings disguised by using his name.
Now sure, there are parts of the current canon that are widely disputed among denominations--those selecting the books for the canon did not extinguish all writings supporting views counter to their understanding, only those which clearly were
The "disputes" as you put it had nothing to do with the content or "views counter to their understanding". The disputes involved whether these books (2Peter and Revelation being examples) were in fact canonical - i.e. meeting the standard of having been written by apostles, chums of apostles, and something else I can't recall at this moment. Neither of the two books mentioned is in opposition to the other books.
You once again put the cart before the horse. The Christian churches all were fond of various writings; over time, all the parts of the church accepted most of the writings that each regarded as particularly significant. They also rejected some writings which were considered non-apostolic, written by non pals of the Apostles, written later, written with false attribution and written in contradiction to Christ.
Some of the most spiritual and orthodox writings that were NOT included were the very popular Letters of Clement, which according to you as products of an early church leader writing the acceptable view, should logically have been declared part of the Bible. Not so. The canon was created
without church-inspired writings of the ruling elders, bishops and what have you. What was chosen included some very problematic things; James vs Galatians for example.
You are actually incorrect - the Catholic Bibles do not "change" the Ten Commandments but translate them as does any other bible (with some alternative word use of course); they are all there. In Roman
catechisms the "no graven images" one is left out because they regard it (falsely) as part and parcel of the commandment to have no other gods before God. Their interpretation is different but the Bible is the same there.
As to gnostics, I don't give a rat's ass for whatever writings they used because their beliefs were contrary to Judaism, to Christ and to God.
For Christianity, by identifying truth with faith, must teach-and, properly understood, does teach-that any interference with the truth is immoral. A Christian with faith has nothing to fear from the facts
