I met with them for 20 years. I had home meetings and went to home meetings. I was a ministry leader. And I gave the message at one of the meetings. But like I said this was a "charismatic" church but a non denominational. When they left the Baptists they were united with a bunch of pentecostals. So it was an amalgamation. We had about 2,000 members.
I don't have any knowledge of the group you met with other than what you said. So the original group was Baptist but then left the Baptist and combined with a group of Pentecostals. I've seen this situation before where groups divide over teaching's and form another group. At the same time though it leads back to what I said about being taught about breaking bread with unbelievers where one portion of a group was observing the others teachings and there was friction over some of it so they split into another group. So which it is I would have to guess since I only have the information you gave but either the group of Pentecostals disagreed with the other's in the Pentecostal group they were meeting with and left or the Baptist group divided. Either way though there are three groups your speaking of with three different teachings one Baptist, another Pentecostal and the third the amalgamation you met with for 20 years.
