Quackodoxy
James Jordan describes what he calls quackodoxy:
Quackodoxy exists between orthodoxy and heterodoxy (heresy). Quackodox ideas are ideas that are wrong but are held by people who are orthodox Christians. If a quackodox idea is pushed far enough and hard enough, it becomes a destructive heresy. Generally speaking, though, quackodox ideas simply trouble the church and make headaches for pastors.
Let me illustrate with several examples. One of the most prominent forms of quackodoxy today is the “home everything” movement. It is fine is you want to practice home birth, for instance, but it becomes quackodox when you try to say that home birth is the best, most Biblical way to have a baby, and then try to pressure other people into it. It is fine if you choose not to circumcise your son, but if you start calling circumcision “mutilation” you are getting pretty close to heresy (calling God a mutilator), and if you start pressuring people about it you are definitely quackodox. You choose to home school? Fine, but don’t say that the Bible teaches home schooling as the best way, because the Bible teaches no such thing. You choose not to use birth control and have twenty children? Fine, but don’t say that the Bible teaches against birth control, because in fact the Bible teaches that family planning is an aspect of Christian maturity (as are all forms of planning).
The Rushdoony-wing of Christian Reconstructionism has a number of quackodox ideas running around in it. One is their belief that the Sinaitic dietary laws are binding as laws of health for Christians. If you choose not to eat shrimp, that’s fine; but don’t try to say the Bible teaches it, because the Bible clearly teaches that Christians are not under these laws. Another quackodox idea that runs through California Reconstructionism is “Biblical geocentricity.” If you believe in a geocentric model of the cosmos, that’s fine; but don’t try to tell me that the Bible teaches it, because it clearly does not.
California Reconstructionists also virtually despise the institutional Church, and in this regard they are close to moving out of quackodoxy into full-blown heterodoxy.
