Greek - ἐκκλησία - ekklésia - 1577 ekklēsía(from 1537 /ek, "out from and to" and 2564 /kaléō, "to call") – properly, people called out from the world and to God
The corruption of the Catholic Concept of the word "church" has nothing to do with the original meaning. The word "church" comes from the Greek κυριακός - kuriakos which means "belonging to the Lord". It's not used for the ekklesia of Christ ever.
The concept of the Catholic "church" is more like the Nicolaitans which God hates.
