No One Has the Right to See Covenant-Breakers Without Permission

"No one has any right to see the Covenant-Breakers without the permission of the N.S.A., and Mrs. … in doing so should realize she is putting herself in contact with a dangerous, contagious, spiritual disease, as the Master pointed out over and over again! She is also disobeying express instructions of the Master and the Guardian by contacting Covenant-Breakers."

(From a letter written on behalf of the Guardian to two individual believers, May 5, 1947)
