I (Pres. Woodruff) was sealed to my father, and then had him sealed to the Prophet Joseph. Erastus Snow was sealed to his father though the latter was not baptized after having heard the Gospel. He was, however, kind to the Prophet, and was a Saint in everything except baptism. The Lord has told me that it is right for children to be sealed to their parents, and they to their parents just as far back as we can possibly obtain the records; and then have the last obtainable member sealed to the Prophet Joseph, who stands at the head of this dispensation. It is also right for wives whose husbands never heard the Gospel to be sealed to those husbands, providing they are willing to run the risk of their receiving the Gospel in the Spirit world. There is yet very much for us to learn concerning the temple ordinances, and God will make it known as we prove ourselves ready to receive it. In searching out my genealogy I found about four hundred of my female kindred who were never married. I asked Pres. Young what I should do with them. He said for me to have them sealed to me unless there were more than 999 of them. The doctrine startled me, but I had it done.
