The Church Growth Movement is a strategy aimed at increasing the size and influence of Christian congregations. It emerged in the 1960s and focuses on understanding the needs of communities to attract new members. This movement emphasizes effective outreach, innovative worship styles, and the use of marketing techniques to engage potential attendees. Key figures in the movement include Donald McGavran, who advocated for studying demographic trends and cultural contexts to foster growth. The movement encourages churches to adapt their practices and messages to resonate with diverse populations, ultimately aiming to fulfill the mission of spreading the Christian faith.
