Why Your Priests Need the Pope Leo XIII Institute

Contemplative Prayer and Spiritual Discernment

Everything the Institute does occurs within the context of contemplative prayer. The spiritual development and prayer life of each priest is the bedrock to this ministry. The Holy Spirit confers the gifts of spiritual discernment necessary to ascertain the presence of evil, and Jesus Christ is the true exorcist who works through the actions of His priests. Thus, at the center of each day is our celebration of the Eucharist and the Liturgy of the Hours.

Improving Fundamental Font of Knowledge

In accordance with psychiatric medicine and formal church teaching, the Institute provides clergy with a font of rudimentary background information and basic knowledge concerning fundamental spiritual manifestations, the myriad types and functions of spirits, and the dynamics of multiple destructive manifestations of evil. The Institute also serves as a forum for ongoing collaboration and support among the exorcists themselves.

Curriculum Development

Relying upon experienced exorcists and theologians, as well as experts in the field of medicine, and psychiatry, law, and education, the Institute formulated a broad curriculum of intensive, in-depth educational programming. With practicums, case studies, and an interactive adult teaching methodology, the Institute coaches the bishop, priest and deacon participants as they strategize their approach in the face of challenging circumstances.

Advancing Professional Approaches, Best Practices, and a Framework for Understanding

Clergy master a basic general theoretical framework of understanding and learn professional approaches and best practices related to confronting demonic forces in varied circumstances.

Monitoring and Consultation

Mentoring and consultation services exist to support clergy and laity in ensuring fidelity with standards of health care and church teaching. We support local diocesan teams in developing effective ministerial strategies and prayerful approaches to engage in all forms of spiritual warfare.

“ I would recommend the Institute for others in this ministry. It has made me realize how much more there is to learn in relation to the healing ministry. The friendship and network of exorcists is quite important. Learning from experienced priests is most important, and also, the time to reflect on this ministry is key to building up our diocesan outreach.”
