Revised Standard Version, mostly the historical books like Genesis, Exodus and the Gospels. The God of the Old Testament and (to a lesser extent) the God of Paul's Letters and Revelations comes across to me as arbitrary, capricious and impossible to please. Like nothing humans do is good enough for Him.
I also read part of the Bible Handbook, although I can't remember the author's name. The book spends entire pages bashing the Catholic Church and the Popes and cozying up to Martin Luther. While I believe that criticisms of the Popes' abuse of power are valid, I don't think those abuses discredit Catholicism. If anything, I believe they discredit authoritarianism and orthodoxy in general.
