Mackey and his companion went to greet their guest. They were impressed by their “golden investigator.” Mackey remembered meeting with Mahlangu for several weeks, each time telling the mission president, Howard C.

Finally, after three weeks, the mission president consented to let the missionaries teach Mahlangu about the apostasy and restoration.*
