First Clement is not addressed to its own readers' problems. It is Rome writing to Corinth, a hundred and some miles and a real cultural distance away by sea, about a dispute the Roman congregation had no formal authority over. Younger members of the Corinthian church had deposed presbyters who, so far as the letter tells it, had done nothing to deserve removal beyond growing old in their posts, and the resulting schism was apparently serious enough that word of it reached Rome and prompted a lengthy written response.
What makes the letter historically valuable is less its theology, which is fairly conventional early Christian moral exhortation, than what its very existence implies about how the earliest churches related to one another. A congregation with no bishop of Rome in the later monarchical sense, writing collectively and at length to correct another congregation's internal governance, is evidence of an inter-church relationship whose exact nature scholars still debate: was Rome asserting a form of authority, or simply exercising the kind of fraternal concern any sister congregation might offer? The letter itself argues from concord and Hebrew scriptural example rather than from any explicit claim to jurisdiction, which is part of why the debate has never fully settled.
Its unusually high early standing, read in some congregations' worship and copied alongside canonical books in the Codex Alexandrinus, shows a period before the New Testament canon's edges had fully hardened, when a text's authority was measured more by how widely and how reverently it was actually used than by a settled list.
