At 94, the “uncrowned emperor” and visionary architect of a reunified Europe carries on a thousand-year legacy of Catholic political leadership
The past and future of Europe have hovered as a haunting subtext beneath all the headlines of 2006. Even as the global encounter with the Islamic world has claimed center stage, the very specter of clashing Christian and Moslem civilizations brings the mind back to Europe – a Europe seemingly in full flight from its Christian heritage just as it stands on the brink of achieving the peace and unity that had eluded it for so many centuries. Europe the cradle of Christendom, where Christianity has become politically incorrect. Europe that stopped Islamic invasions at Tours and Lepanto and Vienna, but where now in some of its countries “Mohammed” is the single most popular name registered for newborn boys. Europe the 21st century’s amnesiac lost child, bent on demographic suicide yet somehow still hearkening to its unique destiny as the heart of Christian civilization…
"In today’s world, it is usually not the person of the pope that is under direct attack, but the Christian faith itself. In Europe, Pope Benedict, like his predecessor, enjoys enormous respect, but the trend in public policies cuts to the core of Christian civilization. When Emperor Karl was in exile, representatives of the same Freemasonry that had engineered his downfall offered to engineer his re-instatement, if he would agree to give them control in just two areas – the education of children and laws regarding marriage. Karl, of course, refused. And yet, the boldest Freemason of Karl’s day would not have dared hope for the policy climate that prevails in the European Union today – where nations contemplating membership are pressured to embrace abortion, where a distinguished Italian public servant was barred from European office for daring to state his adherence to longstanding Catholic doctrine, and where redefining marriage to include same-sex relationships is the latest trend. "
I recommend you read the entire short article to gain a great historical perspective on this, which is stuff you won’t find in most American history classes/books.
God bless you.
