This question already has an answer here:
I am aware that I lack expertise on this topic sorry if the question is badly worded.
There are a lot of reported miracles of the saints in Catholicism reported hundreds of years after Jesus' life, some of which are of-a-form like stigmata and some of which are very unusual like St. Denis having his head chopped off and then walking six miles preaching a sermon.
I would like to know how literally Catholic believers and the Catholic church believe these events to be? Are each of them considered a fact? Or are they thought of more as local stories/heroes or stories of moral instruction or even just there to indicate that a particular person was strong in their faith? Is it considered heresy to suggest that these events are not literally true?
