Warnock has no affiliation to the aforementioned "branch movments"; rather, many have used Warnock's writings (and those of others such as Sparks) to espouse their particular doctrines. Some have been more heretical (universalism, etc.) than others, but we cannot assume that because one uses the writings of someone to teach falsehood that the author is false as well. If this were the case, we'd have to get rid of Paul pretty quickly.For what it's worth, I talked to David Wilkerson in July of '02; when I mentioned that I was also in contact with Warnock, he said, "That man is a true prophet of God."I think in this case, Peter's words apply:"Therefore, beloved, since you look for these things, be diligent to be found by Him in peace, spotless and blameless, and regard the patience of our Lord to be salvation; just as also our beloved brother Paul [insert Warnock, Wilkerson, or other oft-misunderstood teachers], according to the wisdom given him, wrote to you, as also in all his letters, speaking in them of these things, in which are some things hard to understand, which the untaught and unstable distort, as they do also the rest of the Scriptures, to their own destruction" (2 Peter 3:14-17).
