The Jesuits are a Roman Catholic order of priests and brothers founded nearly 500 years ago by St. Ignatius of Loyola. With close to 18,000 priests and brothers worldwide, they are the largest male religious order in the Catholic Church. Jesuits are widely known for their colleges, universities and high schools, but Jesuit ministries also include retreat houses, parishes, hospitals and refugee camps. The USA Central and Southern (UCS) Province serves in 12 states, Puerto Rico and Belize and has approximately 400 men who serve as pastors, administrators, educators, spiritual and retreat directors and in other roles. Jesuits have served in this area of the United States and the Caribbean as early as the 16th century and continually since the restoration of the Society in 1815.
