Met. Kallistos says the same, that the Fathers were silent about women's ordinations (or why men only were ordained). But that doesn't mean we're ordaining women anytime soon. We just have to be honest about that fact that there was no solid teaching against it. At this point we don't have the power to change tradition anyway.
I don't get the impression that Metropolitan Kallistos is in favor of ordaining women, just that he's in favor of coming up with better arguments against it.
According to the interview I listened to (its on Illumined Heart on ACF, by the way), he said the question whether the Orthodox should ordain women or not has not come up yet, so it is a non-issue at this point. But he has not found any Patristic source that favors or condemns women ordination.
That'd be interesting, as I remember a thread about 8 years ago in which we discussed a book about the issue, in which he and other Orthodox theologians had in fact raised the question. I'll see if I can find it...
EDIT--
Found it, that didn't take long...
EDIT2--Reading back over that first quote, I may have misspoke earlier in this thread about what his position is...
