The most important work of the towering intellectual of the Middle Ages, Thomas Aquinas's Summa Theologiae remains one of the great seminal works of philosophy and theology, while extending to subjects as diverse as law and government, sacraments and liturgy, and psychology and ethics. In his third and final part of the Summa Theologiae, Thomas Aquinas begins to address the life of Christ, lived out both in Jesus himself, and in each of the baptized through the sacraments.

Author Biography

An intellectual giant of the 13th century, Thomas Aquinas is best known for the clarity of thought in his philosophical and theological writings. His primary occupation at the University of Paris was as a theologian and a commentator on Sacred Scripture, and his philosophical work was always at the service of his Scriptural meditations. The writings of Thomas Aquinas remain widely influential to this day. "In his thinking, the demands of reason and the power of faith found the most elevated synthesis ever attained by human thought." (John Paul II, Fides et Ratio)
