In order to spot the lies in one's own religion, one must study all other religions with an objective attitude.<quoted text>==========
I have studied Catholicism for many years.
Some writings that I have read include Augustine, Aquinas, Bonaventure,Pierre Teilhard de Chardin, Spellman, Kung (exiled but brilliant) Kempis,Congar,Hildebrand,Rahne r,John Henry Newman, Schillebeeckx,Merton,St John of the Cross,etc.
I studied in Adult Independent Study with a Franciscan sister for 1-2 years.(cant quite remember) She gave me much material on St Francis and we studied from a book "Christ Among Us" and a giant book "Catholicism".
I attended Catholic Mass for about 3 years.
I continue to read and learn.
Otherwise your own religion will keep feeding your ego with the silly notion that YOU own truth.
