Listen to the first chapter of Calvin's Institutes, and discover just how accessible and easy to read it is! (And then, read it!) 

Click on the links below for more of Calvin. Note: the easiest translation of the Institutes to read in English is the Ford Lewis Battles translation (John T McNeill - editor), but the version that is freely available online is the older Beveridge translation. The Beveridge translation is very accurate, but a good bit more difficult to read. So best advice: splash out on the hard copies of the Battles translation - thoroughly worth it!
