“ These apostates talk of proof! Have we not proved Joseph Smith to be a Prophet—a restorer, standing at the head of this dispensation? Have we not proved the Priesthood which he placed upon others by the command of God? I see no ground, then, to prove or to investigate the calling of an apostate, who has always been trying to impose upon this people. It is too late in the day for us to stop to inquire whether such an outcast has the truth. We have truths already developed, unfulfilled by us—unacted upon. ”
