What “cardinal doctrine” means
Christianity includes many churches, denominations and movements. Their worship, organization and interpretation of scripture can differ substantially, yet many recognize a set of teachings as foundational to Christian identity.
The phrase cardinal doctrines is not one universally fixed creed. It usually describes beliefs that a church or Christian organization regards as central rather than secondary. Lists vary according to tradition, historical setting and the authority used to define doctrine.
Some communities treat agreement with every item on their list as necessary for Christian identity. Others emphasize baptism, participation in a worshiping community, adherence to a historic creed, or a personal commitment to Jesus. For that reason, this page describes areas of broad overlap without presenting one community's boundary as binding on all Christians.
Why lists differ
Protestant, Roman Catholic, Eastern Orthodox and other Christian traditions do not always organize doctrine in the same way. Some begin with scripture, others with historic creeds, councils, liturgy or a combination of scripture and tradition. Modern independent churches and para-church organizations may publish shorter statements designed for membership or cooperation.
Differences also arise because doctrinal summaries answer different questions. A brief statement may identify minimum points of cooperation, while a catechism or confession may explain an entire theological system.
