This article investigates the educational role of prayer in Jacek Woroniecki’s works. As Woroniecki (1878–1949) was a Thomist, his philosophical and theological reflection was complementary. In order to reveal the humanism of Christian formation the article concentrates on Woroniecki’s philosophical claims. It consists of six parts. Part 1 defines prayer as a practice and shows that prayer is an important part of human inner culture (formation). Part 2 reveals a relationship, which is vital for prayer, between man and God as a relation between two real and personal beings. Part 3 discusses the topic of relations between grace and nature in man’s growth. Part 4 studies the mysticism of everyday life if man’s actions are considered as a prayer. Part 5 deals with the forms of prayer in the context of the ontic status of man and Part 6 – with the human factors of prayer: the will, the mind, senses and the body. The findings of all those analyses confirm that in the philosophical (i.e. Thomistic) approach prayer is the core of human spiritual growth.
