Lol, I had a nickel for every church called Calvary, I'd be a billionaire. There's dozens of them just in my area.

At the end of the day, you have to do the legwork both to search the Scriptures and check any prospective church against that standard. That's what the Bereans did before they accepted Paul in Acts 17. Churches often have statements of faith or other summaries of their teachings on their websites. That's a good place to start. These days a lot of them have sermon recordings thanks to the lockdowns, so that's another way you can separate the good from the bad before you ever go visit.

If the church you have in mind preaches the Word unapologetically, and doesn't try twisting it to fit their own doctrine, then you probably have a good church. It may take some trial and error, but God will eventually direct you to a local church that's right for you.
