This book is a valedictory study. It follows my five books under the joint title “Footprints of the Twentieth Century” and presents the outcome of further research and reflection on the much broader subject of Europe’s Christian Heritage. As history over two millennia, it is a much more complex and controversial subject than originally thought. Persecution of the Jews dates from the early second century (AD) and continued in modern Anti-Semitism and the Shoa. When the Church becomes the official church in the fourth century and adopts the Roman structure of a single-headed authority, relations with the Jews and so-called heretics become politicized.
