Cardinal Karol Wojtyła, later Pope John Paul II, was an active patron of science, engaging not only financially, but also actively participating in scientific work. His approach to science evolved, avoiding the limitations of rationalism and opening up to transcendence. He adopted phenomenology as a thought method, which enabled him to gain a deeper understanding of transcendence. His attitude to science was strongly related to ecclesial relations and to the understanding of the relationship between science, faith and theology. Wojtyła sought to bring science and faith closer together, seeing the need for cooperation between theology and the natural sciences and humanities. In the Polish Church, as a bishop and member of various commissions, he supported the development of theological sciences and the creation of conditions for independent scientific work of theologians. His activities included initiatives such as Congresses of Polish Theologians, Congresses of Theologians and the establishment of theological faculties with papal rights. Cardinal Wojtyła continued his commitment to the development of science as Pope, emphasizing the importance of ethics and morality. His initiative regarding Galileo and the introduction of the Constitution "Sapientia Christiana" were an expression of concern for dialogue and cooperation between various fields of knowledge. As a patron of science, John Paul II showed concern not only for the development of theological sciences, but also for the integration between science and faith.
