Biblical Word Etymology
The Etymology of “Mystery”
The biblical word “Mystery” traces back to Hebrew / Greek (raz (Hebrew), mysterion (Greek)), where it meant “A divine secret hidden from human understanding until revealed; a sacred hidden truth”. Across 3eras it evolved into the modern sense: “Something incomprehensible or obscure; in theology, a divine truth beyond full human comprehension”.
