I should mention, as I get going on this little endeavor, that in general I refer to Pope Benedict as 'Ratzinger'. This implies no disrespect in any way, shape or form. There is no one I have more respect for than him, and my reverence for the office of the papacy is what any Catholic should have.
However, the works I will be quoting of his date from when he was Fr. Ratzinger, continue through his time as Archbishop Ratzinger, Cardinal Ratzinger, and go up to and include his most recent works as Pope Benedict XVI. All his writings show a remarkable consistency of thought and expression, and I don't want to suggest a sort of retroactive papal authority to all of his life's work. I call him Ratzinger on this blog.
