Doctrines of the church today are no longer needed--as the Father Himself has come.

"A Catholic background is an excellent introduction to the Faith, and one that Mrs. ... should feel gratified for having had. Though doctrines of the church today are no longer needed--as the Father Himself has come, and thus fulfilled the mission of Christ the Son--yet the foundation they lay of spiritual discipline, and their emphasis on spiritual values and adherence to moral laws, is very important and very close to our own beliefs."

(From a letter written on behalf of the Guardian to two believers, August 17, 1941)
