Yep, I would approach with caution, one of the churches listed in my area (less than a mile from my house and the church I grew up in) is certainly not reformed, last time I went there the visiting "evangelist" said "that's right I'm here to talk you into getting saved" This was just after he read John 3:1-7 then "preached" for a minute then read John 3:9-21. Yep he completely skipped John 3:8. I wanted to tear my clothes and run out. Moral of this BE CAUTIOUS
