What does ecumenicity mean?
Ecumenicity is a formal noun denoting the quality of being ecumenical — that is, having a universal character or embodying the spirit of unity and cooperation among the world's Christian churches. It appears most often in theological, ecclesiastical, and academic contexts, where writers may praise the ecumenicity of a joint declaration, a council's decisions, or an institution's outreach across denominational lines. The word carries two closely related senses: first, a general universality or worldwide scope, and second, more specifically, the commitment to interchurch dialogue and reconciliation that defined much of twentieth-century Christianity. It derives from the Greek oikoumenē, meaning 'the whole inhabited world,' the same root underlying 'ecumenical' and 'ecumenism' — the latter referring to the organized movement itself rather than the abstract quality. Ecumenicity is relatively rare in casual speech but remains a precise and valued term in religious discourse.

"The archbishop spoke warmly of the growing ecumenicity between his church and its Lutheran neighbors."
"Critics questioned whether the document's ecumenicity had been achieved at the cost of doctrinal clarity."
Almost never used in the plural; the noun is normally uncountable and appears only in singular form.
Hidden inside 'ecumenicity' is the Greek word for 'the whole inhabited world' — the same root that gave us 'economy,' literally 'household management.'

Etymology of ecumenicity
Ecumenicity comes from the Greek oikoumenē (gē), meaning 'the whole inhabited world,' derived from oikein, 'to dwell,' from oikos, 'house.' The word entered English in the early seventeenth century via Late Latin and ecclesiastical usage, initially carrying the sense of worldwide or universal extent. Its modern association with Christian church unity developed alongside the ecumenical movement of the nineteenth and twentieth centuries. It shares its Greek root with 'economy,' from oikonomia, 'household management.'
