There are numerous definitions of spiritual formation and no definitive depiction due to the breadth of the concept and the numerous perspectives from which religious persons may approach it. From a Christian standpoint, most would argue that it is identical with sanctification as understood as a progressive and gradual process of maturation. It is often referred to as "being conformed to the image of Christ," being made holy, or the formation of virtue and character. In "Care of Mind, Care of Spirit," psychiatrist Gerald G. May offers, “Spiritual formation is a rather general term referring to all attempts, means, instruction, and disciplines intended towards deepening of faith and furtherance of spiritual growth. It includes educational endeavors as well as the more intimate and in-depth process of spiritual direction.”
