She has written, compiled, or made available manuscripts for several books and magazines: Science of Mind, Creative Thought, and International New Thought Alliance.  She has served in many capacities for United Church and is presently on the Hefferlin board which contributes funds for ministerial students and other church and center support. She continues to serve as Member Emeritus for the Science of Mind Archives and Library Foundation that she founded.


Marilyn is available and often participates in School of Spiritual Living classes and presents personal and family stories about Ernest and Hazel Holmes in person and through Zoom.


She is the author of Mother of a Mystic, In His Company – Ernest Holmes Remembered, and Chronicles of Religious Science, Volumes One and Two. She also compiled and edited the book Love and Law and contributed to Conversations with Ernest, and Five Steps to Freedom by Dr. John Waterhouse.
