What is a church?

If I were to ask you, what is a church? You would probably have something in mind that resembles a bit the photo. If I were to ask a passerby here in France that same question, he would certainly agree.

We're a nation with a Catholic heritage. So that photo is exactly what we understand as being a church. Its a big building, where the windows depict stories. The building isn't heated and the benches we sit on are uncommonly uncomfortable (they must do it on purpose), so

much that it comes as a relief when we stand up for part of the liturgy.
There is a priest who does his rounds. But for lack of priests and of
funds, the mass in villages is often held midweek, so that the priest
can hold mass on Sunday in a 'bigger' church. That is a church in the
minds of my people.

In my mind as well, there is often this notion that the church is a
building and something that we do on Sunday morning. God gently
reminded me of the truth during the month of August as I rediscovered
His church.
