Common misunderstandings of the faith

Christian doctrines form the bedrock of the faith, shaping the worldview and practices of devoted followers of Christ. Yet many Americans who identify as Christian hold beliefs that diverge from some core tenets of orthodox Christianity.

Resolved heresies of the Christian faith

Controversies and heterodox beliefs have marked Christianity since its earliest days, prompting intense theological debates as the early Church grappled to define orthodox beliefs about the nature of God, the person of Jesus Christ, the Holy Spirit, and the doctrine of salvation.

The early Church emerged from the theological crises of these formative centuries with clarified Christology and soteriology doctrines that continue to shape Christian theology today.
