Unity, not Uniformity

It's good to remember that despite what seems to be the message coming from many pulpits, unity does not mean uniformity. The first form of the first-century church was exclusively Jewish, with Torah-obedience demanded. The next form, beginning within just a couple of decades, was a mixture of Torah-obedient Jews and non-Torah-obedient Gentiles: two groups having vastly different styles and practices, but united in spirit as a single group. Paul makes it clear in Romans 14 that we can have differences, even on issues which one side may believe very strongly about as being "core".
