Missiology

Modern missiology usually dates its own beginning as an organized academic field to a single meeting. The World Missionary Conference held in Edinburgh in 1910 brought Protestant mission societies together to coordinate strategy across denominations and regions, and the conference's own self examination, asking how mission had actually been conducted and with what result, is generally treated as the founding moment of missiology as a distinct field of study rather than simply mission administration.

The discipline's central debate since then has been about the relationship between the message a missionary carries and the culture that message arrives in. Early twentieth century mission theory largely assumed that Christian faith and Western civilization traveled together, so conversion was expected to bring a convert's culture into closer alignment with the culture of the sending church. Later missiology broke sharply with that assumption. Mid to late twentieth century theologians and mission theorists argued instead for what came to be called contextualization or inculturation, the deliberate effort to let a local culture's own language, symbol and social form carry the Christian message rather than requiring a convert to adopt a foreign one. That shift reframed missiology's central question from how to spread a faith efficiently to how a faith can be genuinely at home in a culture without either erasing the culture or diluting the faith, and it remains the field's live methodological argument today.
