Responding to Danaa - Historically speaking, whether you like it or not, Marc is correct. There have been, without question, flares, brilliant flares even (Bonheoffer and members of The White Rose Society immediately jump to mind), of the ethical and the prophetic since Christianity capitulated to Empire. However, in terms of a consistent and contiguous "vibrant ethical tradition," "vibrant" being the operative word, Christianity (or more precisely, Churchianity) has been/is lacking. Marc’s volleys aren’t isolated attacks on Christianity – they are attacks, and rightfully so, on all institutionalized religions, their obeisance to Empire, and the expedient abandonment of ethical traditions. Judaism does not escape unexamined or unscathed, nor does Islam – Marc’s criticism is aimed at empire-serving religions, not people of conscience.
As for “willfully ignorant,” (in terms of Marc Ellis in relation to Christianity) you are, yourself, ignorant of his background and his work. In terms of “how willfully ignorant jewish people” are in relation to Christianity, and that Jews are guilty of “supreme arrogance”, you have just broad-brushed an entire religion – this is how stereotypes are created, nurtured, developed, and transformed into bigotry, racism and genocide.
