1) where does the Bible prohibit us from calling a building a church.
By its teaching of what a church is. We need to be careful to distinguish between Biblical definitions and English definitions, which are not always the same. Our language and usage calls
sprinkling baptism. Should we just accept that and move on as if it is?
2) where have I stated that the Bible says the building is a "church"
Brother, I do not recall saying that you did. If I did and you did not, then I will apologize.
3) many words have multiple meanings - IMHO - many are trying to make a mountain out of a molehill
Perhaps the limits of a forum like this makes it seem so when many are not. Here is an example on my part. What I am suggesting is that we who are students and teachers of the word should be careful that our words line up with the Word. We do not have to call sprinkling baptism or a building a church (yet it is so built into our language, this is no simple matter). However, making our words line up with the Word does not mean we have to go out and challenge common usage in all our everyday conversations. If a person asks me where my church is, I understand what that person means, and so I am just going to say something like "We meet at XXXX County Road XXXX" without giving a dissertation about the meaning of the word church. That is a wholly different context from a discussion here on the Baptist Board, a place where most people come for the purpose of discussing the Bible. The only reason I would answer a person differently about "where my church is," is if the context of the question was already set in something about the meaning of the word church (as opposed to them just calling our building a church and wanting to know where it is located).
