The evangelical church played no part in my working out the cult was wrong.
You misunderstand me, I meant you needed more than still believing the bible was the word of God. You have said yourself that mistake kept you as a theist long after leaving the cult.
We left pre-internet and we found Bible encyclopaedias useful, particularly for the 607-1914 teaching. Also an interlinear of the Old and New Testament in one because it put such a different slant on familiar scriptures. The public library saved our lives, also it's where we found CoC.
