What is the author's style in God in the Dock; Essays on Theology and Ethics by C. S. Lewis?

Lewis' perspective is that of an intelligent, thoughtful Anglican Christian in early 20th century England. He believes that faith and reason are compatible and holds to a very orthodox version of Christianity. He is concerned with defending the faith and converting others to Christianity; he also defends traditional Christian ethical doctrines, such as sexual chastity, a priesthood restricted to men, a strong defense of individual responsibility, sin and an inability to become good on one's own.
