Statement on plural marriage: "Notwithstanding frequent verbal and printed instructions issued by President Joseph F. Smith and counselors to the effect that the solemnization of plural marriages was prohibited by the Church of Jesus Christ of Latter-day Saints, and these instructions having been reiterated time and time again by myself as President, cases occasionally arise where certain individuals are teaching that it is legitimate to enter into plural marriage, and that such marriages can be performed by certain members of the Church claiming to have authority to do so.
"The revelations of the Lord inform us most plainly that there is but one man on earth at a time who holds the keys of this sealing power; namely, the President of the Church of Jesus Christ of Latter-day Saints. As President of the Church, I once again solemnly declare that no man living has the authority to solemnize a plural marriage; and I hereby announce that it is the bounden duty of every Latter-day Saint, male and female, who knows of any such pretended marriage being performed, to inform the proper officers of the Church, in order that the Church's honor may be maintained and that such individuals may be dealt with according to the rules and regulations of the Church and excommunicated therefrom." HEBER J. GRANT.
