There's an inherent contradiction in such a notion. Benedict claims that we should not convert Jєωs because "Israel has it's own time." A question, your Holiness, what of all the Jєωs prior to this vague time somewhere off in the future? Are they all to be damned, until that one group of future Jєωs collectively referred to as "Israel" gets access to God's Mercy? Either he holds that they are saved currently by some means, or that they are all damned. Obviously, he would reject that latter, so he must hold the former. Thus, speaking about an eschatalogical event that negates any work today is simply a clever way to avoid the demands of the Gospel. So he holds that Israel will be converted in the future, but is already saved, ergo, the contradiction.
