My JW friends (I am not a JW, never have been) all seem to be under the assumption that all other churches do not like each other. They don't get along. That is why there is a Baptist church here, and a Lutheran church there....etc....
I belong to a community church that is non-denominational, and this belief is just not true. Many of the area churches, including our's, participate with and encourage each other. We do not hate each other at all. Quite the contrary. I NEVER hear any of the pastors bad-mouthing each other, either.
My JW friends CONSTANTLY bad-mouth and make fun of other denominations. They claim that all these other churches want is your money. Not true!!! Our church does not pass a collection plate. Money is rarely ever mentioned. They do, however, give us a periodical accounting of how much money has been received and where it all went. (Church expenses, missionaries, local charities, etc...) When I asked for this info. from my JW friends, they came up empty handed. Where is all the WTS money going???? Don't they give an accounting to the people of where all this money is going? I heard they are VERY well-to-do. What kind of charitable giving are they involved in? How many hungry and poor do they feed and clothe?
Where do they get the idea that all churches hate each other, just because they don't believe the same exact way? (Romans 14:2-5) Doesn't this say that it is okay to differ on certain religious issues? We are all still in unity on our core beliefs, which is the Gospel as it is presented in the Bible. We don't have to be exactly the same in order to get along.
I feel this is a common misconception among JWs. Did you find this to be true also?
