Heber J. Grant, Letter to Henry H. Rolapp (Stake President) 28 June
1928 - HJG Letterbook, LDS Archives.
"No rule in the Church that only priesthood bearers could carry the
sacrament to the congregation after it was blessed. While it was custom
for priesthood men or boys to pass around the bread and water it would
in no wise invalidate the ordinance if some worthy young brethren
lacking priesthood perform it in the absence of ordained boys and he had
no objection if it were done."
