The Pope Leo XIII Institute is comprised of four modules spanning two years; each module consists of an intensive 10-day session of prayer and study.

The following topics provide an overview of general course studies that are sequenced to provide the learner with the foundations of the Church’s teaching and practice in the ministry of exorcism.
