About Us


All the staff at CEPHAS are voluntary. They are motivated by the shared desire to create a space for a renewal of philosophy and theology – as a vital and living tradition – in the U.K.

Sister Valery Walker, O.P.

Workshop Leader

Sr Valery is a Dominican Sister with the English Congregation of St. Catherine of Siena (Stone, U.K.). In the early 1970s, she was introduced by Fr Romuald Horn O.P. to a particular method of studying the Summa Theologica of St Thomas Aquinas.

Sr Magdalene Eitenmiller, O.P.

Workshop Leader

Sr. Magdalene is a Dominican sister with the English Congregation of St. Catherine of Siena (Stone, U.K.), based in Cambridge. She received a Master’s degree in Theology (Ave Maria University, Florida), and the Licentiate in Sacred Theology in Thomistic Studies (Dominican House of Studies, Washington, D.C.), and she is currently pursuing doctoral studies with the Pontifical University of St. Thomas Aquinas (the Angelicum) in Rome. She is the author of “On the Separated Soul according to St. Thomas Aquinas,” Nova et Vetera 17.1 (2019):57-91 and “Grace as Participation according to St. Thomas Aquinas” New Blackfriars (2017): 689-708, among other publications

Sr. Magdalene teaches courses on the thought of St. Thomas Aquinas online, and has developed a website called Thomisticstudies.org, as well as a Youtube channel, Facebook, and Instagram pages.

She believes that theological studies can help one develop a deeper union with God and strengthen one’s faith, especially when learning from the teachings of Aquinas, one of the greatest theologians of all time.
