I served an LDS mission in Guatemala in the late 1980s. As my mission progressed, we began to average over 700 baptisms per month, with some companionships baptizing over 40 in one month. When I confronted my mission president about the issue–the response wasn’t what I hoped it would be. After returning home, I wrote a letter to Elder Dallin H. Oaks. Today we claim 12+ million in the Church, but truth be told, less than 1/2 of them actually consider themselves Mormon….and thus perhaps the reason why activity rates are so closely guarded.
