I have just finished reading a book about the history, the story of the formation of the Christian Creeds. For the first time, I have started seriously engaging with theology and I have realised that it can do a lot of strange things to your mind. I realised two and a half things:
1) When you start to pick apart Christianity you get to a whole bunch of paradoxes. This reminds me that (1.5) theology is not supposed to make you believe in God, but to explain Him.
2) We believe a lot of things which are over-simplified versions of much more difficult to explain things. My example of this is that Jesus is not really God despite that fact that this is what almost all Christians believe.
