The Ubiquity of NT Teaching

Recently someone asked, more or less, the following question: “How do we know that the things that were done in one church in the first century were done in the other churches as well?” That’s a good question because if we can’t know that the things practiced, say, in Corinth, were also practiced in Rome, then we can’t really know that we ought to practice the same things that they practiced in religion today.

A VeryImportantPost. Many claim that there's such a diversity of teaching among churches of the NT that it is wrong to hold to a unity of gospel doctrine
