Yep. Mainstream Lutheran: BAD. Missouri Synod: GOOD.
As for my own churchgoing, I tried to attend a Bible study at Lighthouse Ministries south of my town last week, but nobody was there. The sign outdoors hadn’t been changed in awhile, so maybe that church is going bye-bye. Maybe Cavalry United Methodist downtown near my house would be a good fit, especially since the African delegates helped preserve various traditions in the Church as a whole earlier this year.
Ironically, the sign outside LM says, “In case of Rapture, this sign will not change.” As far as I know, there has not been a mass disappearance of devout Christians lately.
For the Methodists, don’t hope for too much, most of the American churches are thoroughly heretical.
Looks for the rainbow, it’s usually in a flag or banner or vestments or altar cloth. If you see it it is a sure sign the church is controlled by Satan. God is gracious in warning us about Satan’s presence, although these deluded people think the rainbow is a symbol of “Pride” and that somehow that is good even though it is a deadly sin.
There's a Community Bible Study in Westminster, in Gaithersburg, and in Bethesda. Classes starting in September. CBS is really, really awesome. There are day groups and evening groups. Get in touch thru the web sites linked above and see what works with your schedule. There is an affordable fee, but that gives you amazing study materials and lots of program extras.
