I am looking for a word like ecumenical:
Ecumenism refers to efforts by Christians of different Church traditions to develop closer relationships and better understandings. Wikipedia
What I want is a word that means the same but encompasses all world religions instead of just Christian denominations.
I am convinced that the lack of such a word is at the root of so much of the world's conflict. I expect I will have to coin a word which facilitates cooperation among the world's religions thus modeling the target behavior for their adherents.
I found: latitudinarian
: not insisting on strict conformity to a particular doctrine or standard : tolerant; specifically : tolerant of variations in religious opinion or doctrine Merriam-Webster
Tolerant is not sufficient. I want a word that connotes active engagement.
