In his book, "The Science of Mind", Ernest Holmes stated "Religious Science is a correlation of laws of science, opinions of philosophy, and revelations of religion applied to human needs and the aspirations of man." He also stated that Religious Science/Science of Mind (RS/SOM) is not based on any "authority" of established beliefs, but rather on "what it can accomplish" for the people who practice it. Today the International Centers for Spiritual Living, the United Centers for Spiritual Living (which combined into the Centers for Spiritual Living in 2011) and Global Religious Science Ministries are the main denominations promoting Religious Science.
