Philip Schaff Quote

Here's a quote from Philip Schaff's History of the Christian Church (which, incidentally is avialable electronicly as an addon to the Online Bible). The quote is about Fredrick II and his experience in what is commonly known as the 5th Crusade.

Thus we have the singular spectacle of the chief monarch of Christendom conducting a crusade in fulfillment of a vow to two popes while resting under the solemn ban of a third. Yea, the second crusader who entered the Holy City as a conqueror, and the last one to do so, was at the time not only resting under a triple ban, but was excommunicated a fourth time on his return from his expedition to Europe. He was excommunicated for not going, he was excommunicated for going, and he was excommunicated on coming back, though it was not in disgrace but in triumph.
