In his sermons Caesarius treats passages from the Bible, often examining psalms or parts of them. He also relates the movements of heavenly bodies to the destinies of men. His homilies, on the other hand, deal with the evangelical texts of the Sundays and festivals throughout the entire Church year, and are to be regarded as theological tracts and meditations rather than sermons and speeches. They are directed not to laymen, but to monks and novices of the Cistercian Order. The interpretations often deal with the lives of monks.
