He says that unless the Pope has canonized them, Rome does not recognize them as saints and we shouldn't either.
Tammy, I would propose that your husband has a less than complete understanding of canonization.
Canonization, while a definitive sign of heavenly presence, carries with it much more.
A Canonized Saint, in addition to dying in a State of Grace, also exibited a life of 'heroic virtue'.
A Catholic might venerate any who now reside at the foot of the Throne. This, by definintion, would include those who have not been canonizted.
A case would be an infant who died shortly after baptism. The infant's family may rightly seek the heavenly intercession of their lost child as a private devotion. The child is truely a Saint, just not canonized. The child's short life would probably not provide much a lesson to the faithful, but the child is still a Saint.
The life of an Orthodox, who , while holy, might have been 'less than charitable' to his Catholic brothers may not provide what some would consider a valuable life lesson, but that a private devotion to one in heaven is ALWAYS permissable.
Besides, you can always tell your husband "Well, he's Catholic now"
