The Divine One is himself the Good (in the primary and proper sense of the word), whose very nature is goodness. This he is and he is so named, and is known by this nature.
Since, then, it has not been demonstrated that there is any limit to virtue except evil, and since the Divine does not admit of an opposite, we hold the divine nature to be unlimited and infinite.
Certainly whoever pursues true virtue participates in nothing other than God, because he is himself absolute virtue.
Since, then, those who know what is good by nature desire participation in it, and since this good has no limit, the participant's desire itself necessarily has no stopping place but stretches out with the limitless.
St Gregory of Nyssa
