ekklesíai
The Greek word "ekklesíai" (ἐκκλησίαι) is the plural form of "ekklesia" (ἐκκλησία). Historically, an ekklesia referred to a gathering or assembly of citizens in ancient Greek city-states, particularly in democracies like Athens. These assemblies were the primary legislative bodies, where citizens could debate and vote on important matters of state. The term itself is derived from the Greek words "ek" (out) and "kaleo" (to call), suggesting a calling out or gathering together of people.
In early Christianity, the term "ekklesia" was adopted to refer to the Christian community or congregation.
