Thomism is the philosophical school that arose as a legacy of the work and thought of Saint Thomas Aquinas (1225–1274), philosopher, theologian, and Doctor of the Church. In philosophy, his disputed questions and commentaries on Aristotle are perhaps his most well-known works. In theology, his Summa Theologica is one of the most influential documents in medieval theology and continues to be the central point of reference for the philosophy and theology of the Catholic Church. In the encyclical Doctoris Angelici Pope Pius X cautioned that the teachings of the Church cannot be understood without the basic philosophical underpinnings of Thomas' major theses:
