Introduction to The Moral Virtues and Theological Ethics (Cessario, 2008)

The New Testament authors may use the term “virtue” sparingly, but, as in so many similar cases, the substance
of the concept pervades their moral teaching. Moreover, ample documentation exists to show that some of the earliest
moral instruction in the Church uses the language of virtue. In fact, St. Augustine spoke about the virtue of Christ
himself as the principal support of the believer’s whole life.
