Interesting and sad story. Unfortunately, its not only individuals that have taken this path, but also churches.
Too many times, I've seen or known of churches that first decided to step away from the "standards", glorying in their newfound "freedom". But check them out a year later and ... their baptism doctrine has changed; their salvation doctrine changes; they begin to tolerate, then accept, Trinitarian doctrine... next thing you know, they're no longer Apostolic any more.
I'm not really extreme myself on the standards thing -- I consider myself to be moderately conservative. But it never ceases to amaze me how so many churches and pastors have started off by leaving the standards, and eventually departing from Apostolic doctrine altogether.
I've seen it happen over and over; I don't have a clear explanation for why one ends up leading to another (since there's no
direct link between the standards and
Acts 2:38/Oneness). I guess in many cases there's just a latent spirit of compromise there, that starts with one area and then ends up leading to compromise in other areas. Just my 2 cents .
