grienspace, I am not a Catholic, nor was I raised as a Catholic; I am an atheist or agnostic or something along those lines. My husband is a ‘lapsed’ Catholic, and all of his family are Catholics - my understanding of Catholic saints comes from these sources. My interpretation may conflict with that of those on this board intimate with Catholicism, but it does provide another POV from which to consider the matter, and therefore may be useful.
Catholics feel that those who live lives exhibiting exceptional devotion to the God of their religion should be honored, and pointed out as examples of what is admirable. After they are dead (which means that they remained loyal to those beliefs to the very end), they are honored by having ‘sainthood’ bestowed upon them.
This is helpful in guiding and advising living Catholics. Many Christians rely on “What Would Jesus Do?” to guide their choices/decisions, but some are discouraged by this because they feel that, as the son of God, Jesus had special insight/incentive/strength, etc., not available to the ordinary person, that supported him in times of doubt and when facing difficult choices. Catholics, however, have an entire roster of once-living, perfectly ordinary humans to point to as evidence that extraordinary things can be done by garden-variety human beings. IMO, this is the primary purpose of having saints - to provide real-life examples for other Catholics to emulate.
Many saints are known for their involvement in a particular issue or activity - perhaps fighting injustice, feeding the hungry, or caring for the ill or injured. These were there primary interests in life; isn’t it logical to expect that they would still be interested in these matters after death? (Remember, only their bodies are dead; the core of their beings still exists in Heaven.) So, certain saints are said to be a ‘patron’ saint of certain matters, as it is thought that they still closely monitor developments in those areas from their place in Heaven.
Because of their exceptional devotion, saints are thought to especially favored by God, sort of a ‘teacher’s pet’ whose judgement God trusts and who God is likely to indulge if they present a special request. Instead of praying directly to God about everything, Catholics may choose to pray to a saint, particularly a patron saint of whatever they are concerned about, and ask them to intercede on their behalf - that is, to present the prayer’s request to God with a note saying that, in the saint’s opinion, the request is legitimate and deserved. Please re-read the formal prayers you posted and see if that is not, indeed, what they are saying.
I don’t see this as any different from someone standing up in church, or posting on a message board, asking other Christians to pray for their mother because she has cancer or some such thing. ‘Prayer’ is not ‘worship’, is it? I was under the impression that it was just a way of talking to God, saying ‘Thanks’ or asking for a favor, and the Catholics simply extend it to include talking to other inhabitants of Heaven.
SDMB Catholics, please jump in here and tell me if I’ve badly misunderstood/misrepresented the matter. I genuinely appreciate being corrected when I’m wrong. No, really, I do! Honest!
