They've been sued and they win. The "church" is only family members. I doubt they know Christ but they do know law. I can't remember all the details but they picketed a soldiers funeral, there was a lawsuit and the soldiers Father ended up owing them $18,000. I think Matt 7: 22-23 applies to people like them.
22 Many will say to me on that day, ‘Lord, Lord, did we not prophesy in your name and in your name drive out demons and in your name perform many miracles?’ 23 Then I will tell them plainly, ‘I never knew you. Away from me, you evildoers!’
Yes I remember now about the soldiers Father. That is beyond shameful. They have no clue as to who Christ is. Are they just covering themselves against some kind of lawsuit by posing as a church? I agree with the verse you posted, Matt 7:22-23 that would definitely apply to them. No one who knew Christ would do such a thing as they are doing.
Also Matt. 7:16 By their fruit you will recognize them.
These people are not my brothers our sisters in Christ. I just hope they see what they are doing before it's to late for them.
