The existence of false teaching in the early days led leaders to develop _____________.

• A. Hospitals
• B. Publishing houses
• C. Educational institutions
• D. Missionary societies

Answer: (D)

When false teaching arises, the leaders seek to extend the church’s reach with clear, unified teaching. Forming missionary societies becomes the practical way to do that: it mobilizes believers, provides funding and structure for outreach, trains workers, and helps establish churches in new areas so people can hear and be taught the correct doctrine firsthand. This outward-focused effort directly counters misleading beliefs by spreading the true message across regions. The other options don’t address the primary response to doctrinal error in this context as effectively; hospitals, educational institutions, or publishing houses may play roles, but a coordinated missionary movement expands reach and accountability to guard against false teaching.
