My wife and me went to a number of Services in different denomination Churches when we first left, we were invited for a number of reasons by friends who attended those Churches.
By that time we were both atheists, and went out of respect for friends. It was noteworthy to us that a friendly welcome was given to us, though strangers, in each, and it seemed genuine and warm, whereas in a J.W K.H there was a forced friendliness and a wariness, "Who are these "worldly people" ? ".
One independent Church we went to, twice, the building had been a traditional Church of England Parish Church, but had been taken over by a group of local Christians, and was run by a wonderful guy, who was a great speaker. The content of his "Sermons" was always about practical Christian living, how we could help each other, AND the wider community, even people in need overseas.
The welcome there was the warmest we had received. It was a vibrant community of Christians, mostly families, nobody dressed up as we J.W's were expected to do back then, I was the only guy wearing a Tie ! even the Preacher had an open necked shirt, the older kids all sat together.
If we had been of a mind to join a Church, that would have been our choice. I even liked the Christian Band that sung and played, what an Atmos !
This is what the Org. seems to be aiming for, but what they will never be able to do is fake sincerity.
