Since his election to the papacy in 1978, Pope John Paul II’s incomparable theological thinking has exercised a vast influence upon the Catholic Church. His documents command worldwide attention because he presents the Tradition of the Church in an accessible way to contemporary readers. The Mystery of the Trinity in the Theological Thought of Pope John Paul II investigates all the papal documents, including his Encyclicals on the Father (Dives in Misericordia), on the Son (Redemptor Hominis), and on the Holy Spirit (Dominum et Vivificantem). In detail, this work systematically presents John Paul II’s philosophy of the human person in relationship with the Divine Persons, his theology of creation and redemption, his Christology, and his theology of the Holy Spirit.
