Catholic, protestant, Muslim, Buddhist ug unsa pa na. Basta they did something good. They're Saints for me. I am Roman Catholic but I don't look down on other religions.
As for incorruptible bodies, yes it's common sa Catholicism and murag puro sa Catholico since we are particular with this while other religions are not. Some religions even cremate the bodies right away. Murag gi tangal naman tingali ng incorrupt body as basis for Sainthood. I'll double check though.
But I still believe naa dyud ana dili ma explain and maybe it's really a miracle. It doesn't give us the right though na ipang hambog na nato and I look down uban religions.
