Orthodoxy and heresy are interesting things.
Over the past year or so, I’ve come to believe that the limits of true Christianity are often inscrutable. That is, I’m willing to count not only the orthodox as true believers, but also many heretics, as well. I’m finding that this position is becoming increasingly hard to hold without some measure of doublethink. On the one side of things, the weight of church tradition stands firmly on the side of a sharp distinction between heresy and orthodoxy, with only the orthodox being counted as true believers. But on the other hand, the weight of church history stands firmly on the side of pluralism, because if only the orthodox are true believers, then no one is a true believer.
On the one hand, church tradition. Ever since Justin Martyr’s denunciation of Marcion in the second century, extending all the way to contemporary culture warriors, the church has had a strong tradition of heresy-hunting. This view makes sense for two reasons. First, in order for an ethnos (a “people,” which is the way the early Christians saw themselves — as a race) to be a true ethnos — that is, for all the members of the ethnos to share common practices — ethnic boundary markers must be in place. It must be very clear who is and who is not part of the Christian people. By necessity, that entails defining what is right practice (orthodoxy) and wrong practice (heterodoxy/heresy) and setting those up as religio-ethnic distinctives. Second, this view is the most scientific. According to the scientific method, a hypothesis is either right or wrong — there is no “maybe” in a rigorous description of how the world works. Likewise, since God is knowable and has revealed himself objectively, it is possible to determine exactly what modes of worship and service he finds acceptable and which he finds unacceptable. Therefore, we may distinguish very easily between right and wrong worship.
On the other hand, church history. Since 1054 CE, every Christian has been a heretic. (1054, of course, was when the Great Schism took place, with the Eastern and Western churches excommunicating each other.) To an Eastern Orthodox Christian, Roman Catholics and Protestants are heretics. To Catholics, Protestants and the Orthodox are heretics. To Protestants, Catholics and the Orthodox are heretics. Each subgroup of Christianity has claimed to be the only right way to worship God. The problem, of course, is that each side uses the same text (the Bible) to support their views, and each side is deeply convinced of their own superiority over the others. So, among the Christian churches, it is impossible to distinguish between right and wrong worship.
Thus, the two sides rage inside me. It is intensely difficult to believe, based on church tradition, that there is a distinction between acceptable and unacceptable worship, while also believing, based on church history, that it is impossible to know what that distinction is.
