What does a missiological breakthrough refer to?

• A. A temporary church plant led by foreign missionaries
• B. A translation-only effort
• C. A viable indigenous church-planting movement that continues to reproduce intergenerational fellowships that evangelize the rest of the people group
• D. A large number of individual conversions

Answer: (C)

A missiological breakthrough means a turning point where the gospel movement becomes indigenous and self-sustaining, capable of reproducing itself across generations within the culture and eventually evangelizing the rest of the people group. This is best described by a viable indigenous church‑planting movement that continues to reproduce intergenerational fellowships, which in turn reach beyond the initial converts to the wider people group.

Why this fits: it highlights not just conversions or external-led efforts, but a self-propagating pattern of church planting and leadership development within the culture, producing multiple generations of fellowship and outreach. The other scenarios lack that sustainable, indigenous, multiplying dynamic: a temporary foreign-led project isn’t self-reproducing within the culture; translation alone doesn’t establish a church-planting movement; and a big number of conversions, while valuable, doesn’t guarantee ongoing reproduction or reach to the entire people group.
