The Pope never said that the words of Manuel II are his, but that he accepts the principle that one cannot spread faith through arms. Also note on page 7 of the speech and I quote:"The courage to engage the whole breadth of reason, and not the denial of its grandeur - this is the programme with which a theology grounded in Biblical faith enters into the debates of our time. "Not to act reasonably, not to act with logos, is contrary to the nature of God", said Manuel II, according to his Christian understanding of God, in response to his Persian interlocutor. It is to this great logos, to this breadth of reason, that we invite our partners in the dialogue of cultures." http://news.bbc.co.uk/1/shared/bsp/hi/pdfs/15_09_06_pope.pdf Perhaps it might be interesting to remind you that the Crusades started after the Byzantine empire was attacked. It were the byzantines who requested military assistance from Western Europe. Flanders was one of the first regions to send a cavalry contingent.
