You know, I’ve long had this dream that the reconciliation between East and West will be very straightforward: the Orthodox admit that the Romans are right about the calendar, and the Romans admit that the Orthodox are right about everything else.
One evident virtue of your position is that it can fit on a bumper sticker.
Romans do admit that the Orthodox are right about everything else. This is why the Orthodox are admitted to the Holy Communion, and particular Orthodox in practice and theology Churches are in many cases united to the Catholic Church. We think that the clarifications of doctrine that occurred in the West following the Great Eastern Schism do not contradict the state of the Church prior to it, and so should be acceptable to the Orthodox, perhaps after a ecumenical council puts its stamp on them.
