Missiology is the study of how the Christian faith is shared and spread around the world. It involves studying how churches, organizations, and people spread the Christian message and how it affects different cultures and people. Missiology also looks at how different cultures interpret and practice the Christian faith. For example, a missiologist might study how Christianity is practiced differently in Africa than in Asia and how that affects people. Missiology is an important field of study because it helps us learn how we can better share and spread the Christian faith in a way that is respectful to different cultures and people.
