 The Roman Catholic Valentin Tomberg in his magnum opus "Meditations on the Tarot" incorporated many Sophiological insights into his Christian Hermeticism, pairing the Holy Trinity (Father-Son-Holy Spirit) with the Trino-Sophia (Mother-Daughter-Holy Soul), which together he called “The Luminous Holy Trinity”.The book’s Afterword was written by Hans Urs von Balthasar and kept on the nightstand of Pope John Paul II.Johnson (1993) and Meehan (1996) noted parallels between the Russian "sophiological" controversy and the Gender of God debate in western feminist theology.
