[Heber J. Grant]
There is no objection to your marrying the young lady of your choice according to the civil law and later, when circumstances are such that it is convenient for you to do so, you and she may come to the temple to be sealed for eternity.
... I wish you and your bride-to-be much joy in your future lives, and trust that the Lord will add his blessings.
[Heber J. Grant, Letter to Dix W. Price, as quoted in Minutes of the Apostles of The Church of Jesus Christ of Latter-day Saints, 1910-1951, Privately Published, Salt Lake City, Utah 2010]
