St. Alphonsus Ligouri was a bishop and theologian during the 18th century. He became a well known lawyer at the age of 16, but after time of discernment, he decided to enter the seminary and become a priest. Alphonsus spent his early years of priesthood ministering to the homeless and marginalized youth, and eventually founded the Congregation of the Most Holy Redeemer, which aimed to preach to the slums of cities. He died in 1787, was canonized on May 26th, 1839, and was declared a doctor of the Church in 1871. St. Alphonsus Ligouri's feast day is celebrated on August 1st.
