The Chicago COs, POs and Elders will kick your ass for going into any other faiths church. Period. You will be put on private reproof if not DFd. It is a set up for severe sanctions.
You might as well invite Satan and every demon into your home. And go buy some antiques and put them in your bedroom. And go on apostate websites.
Oh, but you (ae) are already doing that.
Going into a Church, Synagog, etc. is simply not allowed where I am. I have no idea if it is in the literature. It is inviting Satan and other ideas back into your head. Why would the GB allow any JW into another church? For anything? Even a funeral? Or wedding?
They don't want you to see how the other side lives. Simple.
We were absolutely not allowed to go to any funeral or wedding for any Non-JW family member. Didn't matter who. When my non-JW grandparents died? Mass in a church--we didn't go. Period. We went only to the cemetery. For my frigging GrandParents.
JWs are sick.
