The early church was primarily Jewish, but God began to expand His reach to include Gentiles (non-Jews). This change sparked significant discussion and debate within the church.
The book of Acts details the journey of the Gospel, initially spreading from Jerusalem to Samaria, and finally to the ends of the earth. This expansion was met with both resistance and acceptance, and the early Christians had to grapple with questions of how to integrate these new believers into the faith. This marked a significant turning point in the history of Christianity, opening up the possibility of a universal faith.
