What did St. Sophia do to become a saint?

Sophia was the legendary mother of the virgin martyrs Faith, Hope, and Charity. Three days after the death of the daughters early in the second century, Sophia passed peacefully away while praying by their tomb. As her name means wisdom, and her offspring are named for virtues, some writers believer she is a personification of an allegory.

If Sophia actually existed she was declared a saint before the official canonization process was instituted in the 12th century. He would have been declared a saint to the bishop by those who knew him best and were familiar with his life and merits. The local bishop would them make the decision. Today only the pope can declare saints after years of study by the Sacred Congregation for the Causes of Saints in the Vatican. The church does not create saints. Only God can do that. The Church "screens" candidates for sainthood to determine if they had a life worthy of emulation. In other Words, do they make good role models. Also, the Church has to be assured that the person is actually in Heaven. That is the reason that today a number of miracles must be verified before a person can be declared a saint.
