Our Practitioners

How They Can Support You In Your Journey  The role of a Licensed Professional Practitioner of Religious Science is to help people make changes in their lives by making changes in their consciousness. The fundamental tool of the Practitioner is Spiritual Mind Treatment, also called Affirmative Prayer. Our Practitioners are specially trained to foster a deepening awareness of a loving Presence and inner peace among all who call upon them for support. Working with a Practitioner can help you work through challenges in your life and learn how to sustain results. It can also be an opportunity to expand and increase existing good experiences in life.

Our Practitioners serve CSL Metro in many ways, including Sunday Service and Sunday Morning Meditation. They are available for individual affirmative prayer after our Sunday service and by appointment. Practitioners are available on a professional fee basis for individual spiritual support and affirmative prayer. All interactions and information provided is kept confidential.
