Ok, so I finally saw the sign that a couple of people mentioned. Let me go over this a bit.
Is the sign actually an advertisment for a church, thus making it a public church, as both Jordache and Natulis seem to think? Or, is it being a tool to witness?
First, in one city I lived in a few years ago, there was a house that had Bible verses and other Christian signs on it's fences. This did not signify that it was a church. It was just a method that the people chose to witness to others.
The sign in front of the house does not say anything about a church being held there. So, before one could conclude that the sign was advertising a church there, there needs to be other clues. Clue no. 1 is the sign itself. The type of sign that's on the property is the type that normally buisnesses use. I have never seen something like that in a home. The ones I've seen have been cardboard. Clue no. 2 is the cross standing next to it. Now, neither of these two clues (evidence) actually mean that there is a church there. But, the cross is usually a symbol of a church. Or at least one many people associate with churches, and not just decoration for the front of a home. So, while neither one does actually mean an advertisment for a church, one might concievably draw a conclusion that indeed a church was held there. So, in a way, it might make it public.
The one problem though, is that if you could only attend by invite, then it no longer becomes a public church, but remains a private Bible study or gathering, or does it? I guess that is the question now. Does the fact that a cross in front of the house and a sign that says "There is always hope in Jesus" autmatically make a gathering place a public church?
Natulis and Jordache, thanks for making me aware of the sign.
