Which term refers to the body of Christian doctrine established through both Scripture and Tradition?

The term that refers to the body of Christian doctrine established through both Scripture and Tradition is dogma. Dogma represents the core beliefs that are formally articulated by a religious authority and are considered authoritative teachings of the faith. In Christianity, these doctrines are derived from the Bible and the teachings passed down through the tradition of the Church, thus establishing a foundation for what is accepted as essential truths of the faith.

Understanding dogma is key because it encapsulates the beliefs that all adherents of a particular faith tradition are expected to accept. This collective agreement on doctrine helps unify believers in their understanding of their faith and guides their practice and teachings within the community.

The other options touch on related concepts but don't specifically refer to the consolidation of belief through both Scripture and Tradition. Gospel refers to the accounts of Jesus' life and teachings, the Magisterium describes the teaching authority of the Church, and Apostolic Succession refers to the lineage of bishops traced back to the apostles. Each of these concepts plays a significant role in the Christian faith but does not directly denote the body of doctrine created from Scripture and Tradition.
