Well, I have to agree with Greg, that one cannot "throw out" the opinions of the fathers, just because they happen to have used intemperate language. St. Jerome was notorious for it, but I doubt either Keble or Ebor are prepared to dismiss him, in general. On the other hand, his opinions expressed in highly intemperate language, when they involves, e.g., rabid anti-semitism, are widely ignored even by faithful Orthodox theologians.
But, Greg, not being Protestants, don't we have to recognize that those chiefly responsible for interpreting the Fathers and applying them to the modern circumstances of the Church, are the bishops, to whom we owe obedience? Certainly, we need to read the Fathers, too, but, if my interpretation of the Fathers does not reach the same conclusion as my Bishop's, don't I still need to give him the benefit of the doubt? Especially, when that opinion (i.e., that the following of the Revised Julian calendar need not, at least, render one excommunicate) is shared by all the current patriarchs of the Orthodox Church nd the vast majority of her other bishops?
