Not To Be Confused With
“Sacred Tradition” (capital-T, the apostolic deposit) is not the same as mere human “traditions” (customs), which Jesus criticized when they nullified God's word (Mark 7).
The Greek behind it is paradosis, “what is handed over.” Catholics and Orthodox see Tradition and Scripture as together carrying the one apostolic faith; Protestants affirm tradition's witness but hold Scripture as the final norm — the heart of the Sola Scriptura debate.
