Why did early Christians begin writing Gospels about Jesus?

Early Christians began writing Gospels to preserve the traditions of Jesus’ earthly ministry and Passion, transitioning from oral transmission to written accounts to serve the needs of the growing church. These narratives were shaped by several key factors:12

• Inspiration of Belief: The primary purpose of these accounts was to inspire faith in Jesus as the Christ, his message of the kingdom, and his Resurrection.1
• Loving Curiosity: A deep reverence for and preoccupation with the figure of Jesus created a desire to document his life and teachings, moving beyond the initial creedal affirmations.1
• Theological and Community Needs: The Gospels were molded by the specific theological perspectives of the evangelists and the situations of their addressees, such as the need for admonition, church discipline, or missionary instruction.12
• Anchoring Faith: By incorporating the Passion narrative with accounts of Jesus' earthly life, the Gospel form—standardized by the Gospel According to Mark—anchored Christian faith in the historical reality of Jesus, ensuring that his humanity remained central to the proclamation of the New Testament.2
