As Catholics we acknowledge that a saint recognized by the Church is a dogmatic fact, not simply an honorary title - i.e. a saint is one who with the certainty of faith has achieved the prize of heaven and is meant to be a model for us in the Church militant. Usually this is done these days by a formal canonization process. What, however, are we to say about holy men and women from other Churches who seem to fall outside the pale of the Holy See's processes? I am thinking in particular of the Orthodox Eastern Churches which have maintained the cult of saints throughout the centuries. More specifically I want to point out an extremely interesting event in the Catechism of the Catholic Church. In this book it is possible to find 3 surprising footnotes which one would not except to find in an official Catholic publication. These are the quotes from St. Simeon of Thessalonica, St. John Cassian, and St. Isaac of Nineveh. None of these men were ever honored with the title saint by the Catholic Church, and when one studies their history, we can see that the Church was positively hostile to some of their stances and formulations. This makes it all the more surprising that they should be listed here as saints! As far as I can tell, nobody has spotted this theological development, even though it could have very important ecumenical consequences. Anybody have any insight here?
