Early Life and Calling of St. Gregory of Nyssa
Gregory of Nyssa was the younger brother of St. Basil the Great and one of the three Cappadocian Fathers who defended Nicene orthodoxy against Arianism.

The Second Council of Constantinople honored him as a pillar of orthodoxy.
The vocation of St. Gregory of Nyssa reminds us that holiness is not the exclusive domain of monks and nuns but the universal call of every baptized Christian.
