The Church remembers two of the towering figures in its history today — St. Basil the Great and St. Gregory of Nazianzen. They, along with Basil’s brother Gregory of Nyssa, provided the intellectual, philosophical and theological foundation to explain biblical faith. From the beginning Christians have believed that Jesus was truly the Son of God and truly a human being. But a lack of definition of what that means led some believers to treat Jesus simply as a superior human being on the one hand and other believers to doubt that Jesus really endured all of the limitations of humanity. These great saints developed the vocabulary we use to this day to explicate the great mysteries of salvation — that Jesus is truly the Word made flesh.
