The Order of Saint Dominic, also known as the Dominicans, is a Roman Catholic religious order founded by Saint Dominic in the early 13th century. Its primary mission is to preach the Gospel and combat heresy through education and scholarship. The order emphasizes a life of prayer, community, and study, and its members are often involved in teaching and pastoral work. Dominicans are recognized by their distinctive white habits, which symbolize purity. The order has produced many notable theologians and saints, including Saint Thomas Aquinas. Today, the Dominicans continue their work worldwide, focusing on social justice, education, and spiritual formation.
