(Cont'd)
In quiet faith, let us welcome Jesus as our mentor, as a resource rather than as a "front", barrier, or concetrized, boxed and sealed but rather as "open".  God so loved us that He sent His only-begotten. That love that God sees is His image and we must re-find that image in ourselves (as Jesus did) if we are to really join the Christ we profess. We sorta have gotten it backward. 
So back to the opening: civility is the "how" of  mutual interdependence, that makes sacred space possible.  It ranges from accommodation, to community, to friendship and the intimacy of love. "Sacred space" in individual churches is learning how, safe, so sacred can be possible. Discernment relates because is helps us understand, weigh, contextualize; to distinguish between emotion, presuppositions, bias, fabrications and prevarications,  external influences and judge (as Wordsworth defined poetry: emotion recollected in tranquility). 
Maybe it should avoid the term "ecuminism".
