The spread of Christianity into North and South America can be explained best through the theme of: region. location. movement.

The spread of Christianity across the Americas can primarily be attributed to the theme of movement. European colonization in the 15th and 16th centuries brought with it missionaries eager to share the Christian faith. This movement of people not only facilitated the faith's introduction across vast regions but also led to the blending of indigenous beliefs with Christian teachings, shaping unique expressions of spirituality in both North and South America. Another significant aspect is how the movement was heavily influenced by trade routes and exploration. As Europeans explored new lands, they established connections through trade, which included not just goods but also ideas and religious beliefs. The desire to spread Christianity often accompanied the pursuit of wealth and power, resulting in the rapid and widespread adoption of the faith throughout the continent.
