Two schools of religious thought are orthodoxy (“right belief”) and orthopraxy (“right action”). Religions tend to employ one, the other, or both. Heathenry is an orthopraxic religion, meaning it prioritizes experience, integrity of practice, the creation/continuation of lineage, and legacy as staples of its approach. This is different from an orthodox religion, which prioritizes faith and adherence to creeds, dogmas, and doctrines.
“Right action” also means something a little different in a decentralized religion. “Right” is generally defined by what’s “right” for the individual, as opposed to what’s “right” according to an authority. While some lineages have long-observed customs and practices, these are specific to that lineage as opposed to Norse Heathenry as a whole.
