Final answer:
Evidence for candidacy for sainthood in the Christian tradition includes a virtuous life and miracles, with the latter serving as significant signs of divine favor and evidence of a person's holiness.
Step-by-step explanation:
In the process of canonization within Christianity, evidence of someone's eligibility for sainthood traditionally includes factors like a virtuous life and sometimes intellectual contributions. However, one of the key factors considered as proof of an individual's candidacy for sainthood is the performance of miracles. This emphasis on miracles is rooted in the belief that they are signs of divine favor and confirmation of a person's closeness to God. Many religions of the West, including Judaism, Christianity, and Islam, view miracles as essential elements that substantiate their faith and historical claims, as they are seen as direct interventions from a supreme Being. The Christian tradition, in particular, has been very cautious about recognizing miracles because any challenge to their validity could potentially undermine faith in all such divine phenomena.
