Reformed Christians should reject outright the aberrant teaching known as “Federal Vision” (FV) theology (AKA “Auburn Avenue Theology”).
As R.C. Sproul said before the PCA’s 35th General Assembly (2007):
“I can’t fathom why there’s any hesitancy about [rejecting Federal Vision]. There’s too much at stake—this is the Gospel we’re talking about.”
So far the ARP, OPC, PCA, RCUS, URCNA, OCRC, WPCUS, RPCUS and the RPCNA have all made public statements rejecting the FV. Some are bold enough to call it (rightly, in my opinion) “heresy.” Below are some resources and helps from Reformed synods, study groups, etc. explaining in detail why Federal Vision is an aberration that should be avoided and moreover, resisted by godly people.
