Like many of you, the sound of books dealing with the period after the first century leaves me wanting, but here is a book that is quite helpful in researching the beliefs of the early church.
Have you ever wondered what those of the first two centuries believed on different issues? This work allows you to look up doctrines and topics. For example, my daughter-in-law is Seventh Day Adventist. She kept telling me that the church never worshiped on Sunday until after Constantine. Well, I looked up Sabbath and Lord’s Day and found all kinds of brief quotes, such as one by Ignatius from about AD 105. In fact, there were 14 paragraphs by different church fathers before Constantine’s time showing clearly that the church was worshipping on Sunday. This is one of those works that won’t just sit on your shelf. It is worth having and worth referring to often.
