Good to know.I recall at least a couple of instances but I'll have to look.
Here's what I recall [and he wrote that way about all the guys he blasted on the KJB issue], something to the effect that in such-and-such area, John R Rice was good and I couldn't teach him anything.
If you want more concrete proof, a Ruckmanite Bible Institute (one at least) makes his book "The Home" mandatory reading.
Using that word "apostate" in and of itself is highly offensive. But the truth is, JRR almost never mentioned Ruckman, since he had a personal principle of not answering personal attacks. But really, why even interact with someone who calls you all the names Ruckman called JRR: "Bible rejector," "used of Satan," "blockhead," "naive and shallow," "stupid," "liar," "blasphemer," and "hypocrite."Ruckman repeatedly insisted that just because a man was wrong/weak/apostate on one issue did not mean he was so on all and that God wasn't using him. He just never got the same kind of slack back from those guys because they were too offended.
Yep, I guess Peter just wanted to be friends.

JRR's position on Ruckman was separation, based on the KJV:
"But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat" (1 Cor. 5:11).
