In other words, the Bible is thoroughly corrupted by human hands and minds, agendas, prejudices, etc.
Surely you do not believe this.
That there are some differences in the versions, translations, autographs, etc. ... is undeniable.
But those differences are a very small percentage of the text of scripture.
The basics of scripture ... for instance, that which was encoded in the early creeds (i.e. Apostles', Nicean ...) ... is unambiguously agreed upon by the whole of Christianity.
I would say that everything else ... is peripheral to the basic gospel message.
And I would say further ... if one cannot trust the scriptures to adequately proclaim the gospel of Jesuus Christ (because of these minute difference within the texts), ... how is it that one would trust the communities (i.e. churches) which are responsible for this so-called corruption ?
