If a sister Church such as the Russian Orthodox or the Coptic were to acceded to full communion with Rome, would they be allowed to bring their Saints and Blesseds with them, supposing that they are in fact in heaven albeit that they died out of canonical communion with Rome? For example Tsar Nicholas II and his family, and the four servants murdered with them at Ekaterinburg, all venerated in common as Passion-Bearers.
Answer by David Gregson on 10/9/2007:
To my knowledge, that issue hasn't been addressed. I suspect that Orthodox Saints who have been honored for centuries would be accepted without demur, much as were the Saints of the first millenium, before the canonical process was instituted. Those more recently given Orthodox honors, such as Czar Nicholas, might given closer examination.
