From the commentaries on Paul's epistle to the Philippians, much can be gleaned about the circumstances of that period. But what happened in the time after the Philippians received Paul's letter? From the fourth to the sixth centuries, at least five churches were built. Were these churches necessary due to large numbers of churchgoers, or did one or more of these churches belong to heretical groups? This article attempts to provide a plausible overview of the development of the church in Philippi in the period following Paul's preaching there and the end of the sixth century. The famous studies by Collart and Lemerle cannot be ignored, but far more information than what those scholars had access to is now available to us. The recent works by Peter Pilhofer, in particular, are highly instructive. Using new evidence, we can now provide a more detailed history of this church's history than ever before.
