You do know that non-denominational churches are very much denominational LOL
I know a person very well that 20 years ago was a part of a new SBC Baptist church being established in a collage town.
After about 5 years, their growth leveled off at about 300.
They decided to take Baptist off the sign and off all their literature and become non-denominational.
Of course, that was in name only, their teaching did not change,
Within another 5 years they had grown to 500 and now have 800 in attendance.
Where as the collage crowd avoided them as Baptist, they now have a great number of them in attendance.
The day of having a general idea of what a church taught and practiced by the name out front, is long past.
