How many miracles did st Andrew perform?

Miracles were not required for declaring a person a saint in the early

years of Chrisitianity. The person would have been declared a saint by

popular acclamation to a bishop based on the lives and merits of the

candidate. This was especially true if the person died the death of a

martyr as it was felt that making this ultimate sacrifice for Our Lord

would be an automatic designation of that person as a saint.

Even today, miracles are not always a requirement for canonization,

especially in the case of martyrs.
