In this article we carried out a review of religious education based on Ken Wilber’s AQAL model, for which purpose a review of the current understanding of religious education is made, widely equated with school religious education, verified both in magisterial, doctrinal and ministerial documents. This is followed by a review and clarification of the origin of Ken Wilber’s integral model (AQAL model) and then an analysis of the way in which it is applied to all knowledge as its principles state. From this explanation, the analysis of religious education is undertaken in order to broaden the foundations that underpin its understanding, expanding it far beyond school education and encompassing the full breadth of personal, social and institutional religious experiences. It is concluded, through this research, that religious education is a field unjustly reduced to its school dimension and that it can be developed from an integral epistemology to extra-school, extra-ecclesial and, without absolutist intention, universal dimensions.
