From time to time (and now is one of them), I try to envision what is was like for the apostles, disciples and early Christians. Evangelizing the world to a new creed, and putting aside old beliefs and traditions is hardly a piece of cake. Add to that, all of the cultures, languages, and traditions of other nations, and it is bound to become messy here and there. A Christian Greek Jew would have a lot to sift through before he reached a full conversion. So it will probably be in the years to come. Those who take heed to the Warning would do well to study the words from 'Acts'. After the re-unification of the Protestants, the animosity over particular books in the Bible will hopefully diminish.
"Closer to You bid me, that with Your saints I may be praising Your name, forever and ever."
