We spend lots of effort on this board quoting extra-Biblical sources from theologians, scholars, historians, officials of various denominations throughout history, etc. There are lots of quotes from Josephus, Augustine, Luther, Calvin, Pink, Wallace, and so many more. They can range in doctrine from Calvinism to end times, and extend out to things like Bible versions when debating the KJV. Do you think the earlier these writers lived to the time of Christ makes their observations and opinions any more valid than someone who lived later? For example, it seems like when someone quotes Calvin (just an example) and someone counters with a point from Augustine, that most think Augustine's point wins out because he was from a time nearer to Biblical times.
