Heroic virtue doesn't get you into heaven. It indicates that you are richly blessed with the gifts of these virtues to a great degree. The 'canon' of saints is not exclusive. They ones on the canon are just the ones we "know" are in heaven and who are, we deem, worthy of extra whoopee because they are loci and recipients of such wonderful gifts.
Thank you for your questions.
Thank you for commenting on this. I agree fully.
