In opposition to tenants and articles central to keeping the faith, there is the handy Greek term
adiaphora that refers to those matters that one can leave or take—like, I suppose the holier-than-thou high-ground, that goes by
cafeteria Christianity and related sleights. This originally Stoic concept means indifference—neither good nor bad, accepting of a certain latitude or license in organisation and practise—careful, however, not to pollute the conscious of one’s neighbour by lapsed and liberal behaviour. For something considered optional or neutral, there’s a pretty important lesson behind it—sometimes the law does deal with trifles.
