Of all the "heresy hunters" out there, Cloud seems to be one of the more charitable and even-handed while at the same time not trying to excuse the errors. He genuinely seems to be concerned more about promoting sound doctrine (exposing false doctrine) than attacking personalities. Many forget what we are told to do :
Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them.
For they that are such serve not our Lord Jesus Christ, but their own belly; and by good words and fair speeches deceive the hearts of the simple.
Romans 16:17-18
{Paul repeats more or less the same thing to the Philippian church in Philippians 3:17-19}
In this case, he seems to be laying out the littany of 20th century issues in Charismatic circles. By doing so, one can contrast the true with the false. So I wouldn't come to the conclusion from this article that Pentecostalism is of the devil (as Cloud himself says, he came to Christ through the ministry of an old-time Pentecostal whom he calls "godly"). If anything, it's a testimony to the general gullibility (lack of discernment) of those who are Charismatic. Anyone who ever thought Robert Tilton was genuine...
Comparing Cloud's attitude with that, say, of John MacArthur, one finds a more irenic approach. While much of what MacArthur says is true, his line in the sand seems dangerous when he bases his conclusions at least partly on hearsay. Charles Parham was charged with being homosexual but continuously denied it. He was brought up on charges in San Antonio but those charges were later dropped by the DA. In other words, there was never any confirmation - it was an unsubstantiated rumor. But Dr. MacArthur presented it as part of his case against the man and his doctrine. He doesn't say the case was dropped but says he was charged. He uses that to impugn Parham's character. As far as I know, MacArthur never mentions that the charges were dropped. The point being that he's using an unfounded allegation against the man.
Overall, I thought it was a good summary of the weaknesses showing in the Charismatic movement.
