The document discusses key concepts related to developing indigenous churches, including indigenization, enculturation, and contextualization. It describes how historically churches were developed by outside advocates but that a better approach is to guide cultural insiders as they integrate biblical faith into their local culture. It also discusses the three-self formula of self-supporting, self-governing, and self-propagating churches and the role of trusting the Holy Spirit in believers and developing partnerships between missionaries and indigenous churches. Models of relationships between missions and indigenous churches range from missionary control to complete indigenous church autonomy.
