Fascinating review of a biography of prolific Jewish scholar Jacob Neusner here. One of Neusner's emphasises has been on Judaisms rather than Judaism. Reading about that in the review got me thinking: is it better to think "Christianities" rather than "Christianity"?
When we think the latter then, positively, we have people such as moi trying (in an almost inconsequential way!!) to nudge Christians within the one Christianity to ever greater unity. But negatively we have interminable battles as the Church of X and the Church of Y compete for title of "true church" (all the while demonstrating various foibles and fallibilities).
If we think the former, might we stop worrying about unity, cease to compete for title of "true church" and generally chillax?
