[Heber J. Grant]
Regarding to the holding of funerals on Sunday:
We approve of your having recommended to the Bishops that as far as possible funerals be held on week days. However, this cannot be established as a binding rule, and there is no order of the Church prohibiting the holding of funerals on Sunday. When, however, it is deemed advisable to hold funeral services on the Sabbath Day, the hours should be so arranged as not to interfere too seriously with the regularly established Sunday meetings.
