D&C 88

 

As leaders were called to participate in the School of the Prophets, The Lord instructed -

"Tarry ye, tarry ye in this place, and call a solemn assembly, even of those who are the first laborers in this last kingdom."  (Doctrine and Covenants 88:70)

"Therefore, verily I say unto you, my friends, call your solemn assembly, as I have commanded you."

(Doctrine and Covenants 88:117)

The dictionary defines solemn as - 

serious, sincere, sacred, and binding.

Which all religious leadership meetings should be.
