“The only argument the world will listen to now is the argument of personal holiness. It has heard all the rest and rejected them.”
Retreat to Priests, Washington, D.C., p. 19, quoted in Bernard Hayes, C.R., To Live as Jesus Did (Locust Valley, N.Y.: Living Flame Press, 1981), p. 108. There is no book by Sheen with the title Retreat to Priests. Hayes is presumably quoting from a transcription of Sheen's 1974 retreat for priests of the Washington diocese. This was recorded on reel-to-reel tape and later issued in nine 60-minute tapes under the title Renewal and Reconciliation.
