St. Hilary of Poitiers (300 - 368) was born in Poitiers, France to a non-Christian family. He believed in Jesus after reading the Bible. His townsfolk made him a bishop due to his holiness and wisdom. He worked hard to dispel a prevalent heresy that Jesus was not God. He was even banished by the Emperor of Rome for doing this. St. Hilary wrote many books about Scripture and theology. He is ranked a Doctor of the Church. His feast day is on 13 January.
