Here are some Church History resources for you:
I set up a blog that (I hope) can help others explore the Church History in a simple way as I understand it. I have tried to retell the story of the Church in a way that emphasizes the different aspects of our modern, Western background.
II. The Story of Christianity by Justo L. Gonzalez
This is a very good book written to explain Church History. It is highly recommended for those who like to read.
All that we know about Church History we have learned because men in the past took the time to write down their understanding of the times and events they lived through, and I have searched for as many of those writings I could find online for you.
