Final answer:
Christianity spread at varying rates from 600 C.E. to 1450 C.E. Elite Christian thinkers played a role in disseminating religious knowledge and constructing a unified Christian identity. Proselytizing efforts and ongoing participation in defining beliefs and practices contributed to the spread of Christianity.
Step-by-step explanation:
Christianity spread at different rates between 600 C.E. and 1450 C.E. The Early Spread of Christianity can be seen in Fig 15.7. During these years, Christianity expanded widely throughout the Mediterranean world, including northern Africa. Elite Christian thinkers disseminated religious knowledge, participated in ecumenical councils, and worked towards creating a single agreed-upon narrative of Christian identity. The spread of Christianity during this period was facilitated by proselytizing efforts and ongoing participation in defining belief and practice.
