Basil refused to separate doctrine from the life of the church. He fought Arian theology, wrote On the Holy Spirit, organised monastic communities, and built institutions for the poor and sick around Caesarea. His importance is not only that he defended Nicene faith, but that he showed what that faith looked like in prayer, ascetic discipline, preaching, and public mercy. Gregory of Nazianzus and Gregory of Nyssa carried parts of his work forward after his early death.
