What is certain is that the Soweto group waited another two years after the 1978 revelation for baptism. Why? Although LeBaron had been meeting with local priesthood leaders to plan the expansion of proselytizing to black Africans, some missionaries remembered apathy, if not animosity, among some members toward baptizing black converts. Rather than “animosity,” Gerald de Wet characterized the attitude as “caution.” Actively proselytizing black South Africans was unprecedented. De Wet also recalled that his father, who was then the bishop of the Johannesburg First Ward, disagreed with LeBaron over the mission president’s desire to move forward with the baptism of the Soweto group after the 1978 revelation. There do not appear to have been any baptisms of black converts in South Africa during 1978 and only one in 1979. Necessary support from local leaders finally came around March 1980.
The year 1980 proved to be momentous. South African Mission records show that in May of that year, “African” converts outnumbered “European” converts for the first time.
