Ousia

Ousia (/ˈziə, ˈsiə, ˈʒə, ˈʃə/; Ancient Greek: οὐσία) is a philosophical and theological term, originally used in ancient Greek philosophy, then later in Christian theology. It was used by various ancient Greek philosophers, like Plato and Aristotle, as a primary designation for philosophical concepts of essence or substance. In contemporary philosophy, it is analogous to English concepts of nature,[1] being, and ontic. In Christian theology, the concept of θεία ουσία (divine essence) is one of the most important doctrinal concepts, central to the development of trinitarian doctrine.[2]

The Ancient Greek term θεία ουσία (theia ousia; divine essence) was translated in Latin as essentia or substantia, and hence in English as essence or substance.[3]
