I went to my first baptist church at the wipe young age of 5 (I can still see my father driving into the parking lot) I went to that same church (even though it went through many changes in pastors and affiliations (until I was 17 when I went into the military, At that time, I went to many different baptist churches all over the country (michigan, Texas, Northern Ohio, FLorida, Massachusettes)
I can say as for as the church service goes. You can not tell one from another they are all the same (or at least appear the same) It is when you get down to the nitty gritty doctrinal issues that they differ, But unless you are around them for awhile, and get down and dirty with them (deep into doctrinal issues, not just sunday/wed service and involved in everything)
You would never know there was a difference. You would think they were all the same.
