This paper takes into account questions formulated by the Holy Mother. Her thought and consideration on the revealed word serves as pattern of theological thinking and key to understanding of the relationship between theology and other sciences. This study is based on the Church’s magisterial documents, papal teaching, as well as theological and philosophical statements. The matter of theology determines its principles, start point and methods. Its criteria consider the universal requirements of reason but, unlike in other sciences, are deeply and indispensably enrooted in ecclesial community. The purpose also distinguishes theology in the scientific world and confers particular meaning concerning its pragmatism, benefits and importance.
