Being morally or spiritually indifferent; neither good nor evil in itself; neutral.
From Greek 'adiaphoros,' combining 'a-' (not) + 'dia-' (through) + 'pherein' (to bear or matter), literally 'not mattering' or indifferent.
The word 'adiaphorous' appears in centuries of theological debates because denominations fought over which practices were truly adiaphorous (just cultural style choices) versus essential to faith—a debate that shaped religious reform movements.
