Sense: adjective/1
Ecumenical, interdenominational, and nonsectarian all relate to cooperation across group boundaries, but they differ in scope and goal. Ecumenical specifically refers to efforts to promote unity among Christian churches — it carries a theological and institutional weight that the other two lack. Interdenominational is more practical: it describes events, programmes, or organisations that involve members of different denominations without necessarily aiming for structural unity. A choir that draws singers from three churches is interdenominational; a formal dialogue about merging those churches is ecumenical. Nonsectarian is the broadest of the three — it means 'not aligned with any particular sect' and is common in education (a nonsectarian school admits students of any faith). Ecumenical is also used in a rare, intellectual sense meaning 'worldwide in scope', whereas the other two never carry that meaning.

Etymology
From Late Latin oecūmenicus, from Greek oikoumenikos 'of the whole inhabited world', from oikoumenē gē 'the inhabited world'. The Greek word derives from oikein 'to inhabit', from oikos 'house, dwelling'. The Christian-unity sense arose in the 1800s as churches began formal discussions about reuniting across denominations.
