Perhaps he was using the term Reformed as you and Fred are saying? If so, he was not consistent:

MJM said,

A number of reasons played a part in my decision to reject Calvinism…. I became despondent with the attitude and behaviour of certain Christians within the Reformed …. this did not "cause" me to reject Calvinism. There can be a lack of Christ-likeness in both camps (i.e. in Calvinist and Arminian Christians). But it did lead me to re-examine Calvinian theology… I began to doubt my belief in the Calvinian …
Clearly, taking MJM’s words in their context he’s using the terms Reformed and Calvinist, Calvinism, and Calvinian synonymously above. Thus, I do not think his foregoing statements are using the word Reformed in a strict historical sense…., but in a theological one. Of course with statements like, “I wouldn't say that Calvinism is unbiblical" contrasted to "Calvinists are sincerely wrong in what they believe,” it is already confusing at best! <img src="/forum/images/graemlins/shrug.gif" alt="" />
