[John Taylor to F. Spencer, Mar. 25, 1878] You understood Bro[ther] Joseph F. Smith rightly with regard to those only being accepted at the Endowment House who have been re-baptized. We do not think that the blessings of the House of the Lord are for those who are either too careless or too indifferent to give heed to the servants of God, when a call is made for repentance and renewal of covenants. The only exceptions that we make to this rule are with those whose first baptism has occurred within a few (say six or eight) months.
