"Whoever suggested such a thing to you and how did they ever lead your mind astray? ... How, indeed, is the Greek Church to be brought back into ecclesiastical communion and a devotion for this Apostolic See when she has been beset with so many afflictions and persecutions that she sees in Latins only an example of perdition and the works of darkness, so that she now, and with reason, detests the Latins more than dogs?" - Pope Innocent III
