Everyday is Church!

The body of Christ is the Church (ekklesia) of God. It is one under one Head, Jesus Christ. The Greek word ‘ekklesia’ is a word that is translated ‘church’ in the New Testament. It refers to a called-out group of people ('ek'-out from or of; 'kaleo'- to call). The church was never to be about the buildings (an idea that really flourished in 350 AD) or about a certain denomination or organization. It is about people, men and women who are committed to the lordship of Jesus Christ and who exercise the power of God in everyday life.

 Jesus Christ pointed this out in John 4:20-24 when the woman at the well related their conversation to  physical places of worship.  

20 Our fathers worshipped in this mountain; and ye say, that in Jerusalem is the place where men ought to worship. 21 Jesus saith unto her, Woman, believe me, the hour cometh, when ye shall neither in this mountain, nor yet at Jerusalem, worship the Father. 22 Ye worship ye know not what: we know what we worship: for salvation is of the Jews. 23 But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him. 

Stephen in his answer to his accusers states  in Acts 7:48-49:

 Howbeit the most High dwelleth not in temples made with hands; as saith the prophet, Heaven is my throne, and earth is my footstool: what house will ye build me? saith the Lord: or what is the place of my rest?

Today the English word ‘church’ (link) brings to mind a  ‘house of the Lord’. The word for ‘belonging to the Lord’ is another Greek word 'kuriakos'.  John Ayto's useful "Dictionary of Word Origins" (Arcade:
New York, 1990) speaks of this word and it's development:

--*church* [OE] Etymologically, a *church* is the 'Lord's house.' Its ultimate source is Greek *kyrios*... The adjective derived from this was *kyriakos*, whose use in the phrase 'house of the Lord' led to its use as a noun, *kyriakon*. The medievlal Greek form, *kyrkon* 'house of worship' was borrowed into West Germanic as *kirika, producing eventually German *kirche* and English *church*. The Scots form *kirk* comes from Old Norse *kirkja*, which in turn was borrowed from Old English.-- 

History and evolution of word etymology must be responsible for the King James translators to substitute the word ‘church’ in place of ‘ekklesia’ when translating from the Greek texts. Other translators such as Tyndale translated the word ‘ekklesia’ as 'congregation' instead of 'church'. King James actually uses the word 'assembly' for 'ekklesia' in other places.

The first use of the word 'church' is in Matthew 16:18. 

And I say also unto thee, That thou art Peter ( petros- shifting, movable, stone), and upon this rock(petra - referring to himself - immovable) I will build my church (ekklesia, not kuriakos); and the gates of hell shall not prevail against it.

Jesus Christ was not building a cathedral or any type of building, he was drawing people to God through his life. He was and is  building  an assembly or a congregation who will be gathered together when he returns. I doubt very much that the Basilica in Rome or Westminster Abbey are going to be lifting off on that day.  On that notable day all the members of the church of God also called the body of Christ will be joined to the head Christ irrespective of denomination, non-denomination or un-denomination!
