Who is the patron saint of strength?

Saint Christopher is the patron saint of strength. His saint's day is observed on July 25. He began life as a Canaanite man named Reprobus.

Saint Christopher was said to be 7 ½ feet tall. He began life as a soldier for the king of Canaan. He later became a Christian. He used his great strength to help many people cross a dangerous river, and legend tells that he also carried a child version of Christ who was heavier than lead across the river. On his visit to Lycia, he refused to perform pagan sacrifices. After many failed attempts, he was captured and beheaded in 251.
