First published in 1964 and now thoroughly revised and updated this is a seminal work. Father Flannery writes of antisemitism as "a tragedy in which Jesus participates, crucified again in the person of His people at the hand of many baptised in His name". So far as Christians and the churches are concerned this book is hard-hitting, precisely because it needs to be. Nothing less than a "change of heart" (Flannery) is necessary.
