I just went to Frank Viola's website and found an interview promoting one of his books. A small analysis may give insight.

"I have watched people try to start their own house churches who were not called or qualified to do it.In every case, I saw nothing good come of it. Most of these groups were simply glorified Bible studies that were facilitated by the person who started the group....We made many mistakes and tried some very foolish things. But we learned. And in the midst of it we touched authentic Body life......We need a new seeing of the Lord Jesus Christ and of Gods eternal purpose which is in Him.....In other words, we need those who are able to impart life, to cast vision, and to provide practical tools that will put believers into the living reality of that vision."
I am reading a work by someone that uses similar reasoning so picked up on some things right away.
1. First you see what I call a double insult. (Sometimes such statements can be phrased as a compliment hiding an insult.) Those who tried to start house churches without what he names "calling" and "qualification" are doomed to fail, so don't even try. At the same time he insults the concept of bible studies as being something inferior to the house church idea that he is proposing. He is also implying that a bible study cannot be a house church. Why not? "For where two or three come together in my name, there am I with them." Matthew 18:20. With Mr. Viola as subject of the interview, the reader is to accept his authority on the matter and apply it to all that is being said.
2. He admits to making mistakes and being foolish. In this case this is a tactic to wake sympathy in the reader. Other ways of doing this are telling jokes or stories about ones failures, not simply out of honesty, but for a reason - to create sympathy or even empathy. If the reader can sympathize with the author for whatever reason, he will more likely accept what that person has to say.
3. He then states that he found an answer, he "touched authentic Body life". This statement will especially appeal to and draw the emotionally motivated, which are often the easiest to manipulate. He claims to have found the real thing, as so many do, which may trap the so-called "seeker".
4. For the first half of the article he is dismantling the concepts that many think of that hold to the traditional way of conducting a church body. He attacks all groups whether Protestant or Catholic, Charismatic, Third-Wave or traditional. He is performing a miniature version of Schein's stages of cult manipulation called Unfreezing, Changing and Refreezing. For a table see:
http://www.rickross.com/reference/cults_in_our_midst/cults_in_our_midst2.html it will be the second table on the page or go to my page:
http://www.jamesfive19.com/Abuse_of_Pastoral_Authority.html and scroll down to find the table. Make a person unsure of what he thinks of as secure, manipulate him into considering another option and then make sure he keeps that new position. In this case there was probably an offer for his book after the interview which, if bought, would refreeze the person's mode of thought to Frank Victor's view of things. In fact the interview was a miniature version of what is said to be contained in the book.
5. The Changing takes place in all of the above statements but especially with the ones about a need for a new way of seeing God's eternal purpose...after disposing of the old-fasioned, inefficient, undesireable ways, he offers a ray of light that one can grasp for. He tries to impart a new vision that seems brighter and clearer to the reader than that which has been denounced. And who is going to lead this new order? The key phrase is: "We need those who are able....to provide practical tools that will put believers into the living reality of that vision." And that, of course, means him and his materials and program.
The whole article was a sales pitch, offering to impart life and a new vision of God's eternal purpose. That of course costs money (although I ask myself why it should have to, the Holy Spirit didn't cost anything).
I have nothing against people offering products if they can deliver. But in spiritual matters these things can be very dubious. And if someone is purposefully trying to manipulate me in the way I described above, I have a good reason not to trust him from the beginning. And I have not even gotten into Frank Viola's theology yet! This is just the beginning of the analysis process.
