"Revelation finished with the last Apostle, since then no new truths have been discovered or revealed."

Sorry Tridentinus, on this we utterly disagree. I believe the Spirit has been active inspiring humanity, drawing us to God, from the moment we evolved as homo sapiens and we became immortal. I assert that real organic development is evident throughout the OT and in the NT and down through the history of Christian theology. 

In the past I challenged you on this topic re the early Greek councils of the Church. The trinity and that Jesus is fully God and fully human are fundamentally new understandings beyond the death of the last Apostle. It is true, that have accepted those doctrines, we easily read them back into scripture. What we refuse to acknowledge is that at the time of those early Councils, different theologian read different things in the scriptures. 

Here we part ways, and there is no middle ground.
