I put this into General Discussion because although it's a serious question, it's also meant to be a bit of fun too. I'd like to see some creative ideas here.
Imagine that you discovered a new country (like the North American pioneers), or you were forced by war or famine to flee to some remote wilderness and build a new community with just friends and family, or maybe several families.
You set up a new community. You build dwellings and you use local resources - wood and stone. You grow crops and maybe build a village.
You decide to build a church. Maybe it's quite a big church, maybe it is little more than a small chapel.
You are all Christians, or maybe the majority of you are. Do you have a pastor or can one of you act as a stand-in pastor?
Your village may be tiny but after a few generations you are expecting it to turn into a town of hundreds or thousands. If your community gets bigger you may have to build several churches or places of worship - perhaps one day, a cathedral may be built.
But when you are still small - how many people do you need to attend your place of worship in order to call it a place of worship?
The Bible tells us that when two or more people come together and pray, then God listens. So a church is not one man, but at least two.
But is two enough? What about three? One person can be the pastor (but is really just a prayer leader) and the other two are the congregation.
What about four people? That is even better. What about five or six, then you could have a family together - father, mother and children.
My original premise is: What would you do to get your community together as a church? How many do you need before you can be considered to be a church? What would the inside of your humble church be like? Does everyone have somewhere to sit, or is your church so small that everybody has to kneel down?
How small can your church be and still be considered a church?
If your community expands and you can eventually build more places of worship or build bigger churches, at what point do you decide that a church building is full? After twenty people?After fifty people? After a thousand people? You would eventually have to start dividing your community into parishes.
But let's go back to the small again. Is my church big enough with just two people in it, or do I need more people to really call myself a church?
