One Year Foundation Course is the result of many enquiries from people wishing to learn more about the philosophy, theory and practice of 'mediumship' as taught by The Greater World under the banner of Christian Spiritualism. This course creates the foundation upon which you will be able to build your mediumship. The course includes Bible study, Spiritual Aspects of Self-Awareness, an Introduction to Healing, Making Communication with those in the World of Spirit, and Christian Spiritualist Philosophy. Participation in the course is mandatory for those wishing to take The Greater World Study Course for 'Messengers'.

Two Year Messengership Course is for those who have already completed the Foundation Course and is available, not only to working mediums, but to mediums giving private sittings and also to Spiritual Healers.The course is not a replacement for the development of practical mediumship, but an adjunct to it. Students will be expected to persue their own mediumistic development outside the course, following help and instruction received through workshops and written papers. It is important for would-be-entrants to the Messengership Course that by the end of a one year probationary period, The Greater World standard of practical Messengership will have have been reached. All this leads to a Service of Dedication at which the student receives The Greater World Certificate for Messengers (C.G.W.M).
