In The Christian Mind, Harry Blamires identifies six marks of the Christian mind and devotes a chapter to each. They are: its supernatural orientation, its awareness of evil, its conception of truth, its acceptance of authority, its concern for the person, and its sacramental cast. Here's a selection from his chapter on its supernatural orientation:
The Catholic tradition of our Church is that the Christian life is a life for the full man. There is no room in Christendom for a culture of the spirit which neglects the mind, for a discipline of the will which by-passes the intellect. It may be that the dominant evil of our time is neither the threat of nuclear warfare nor the mechanization of society, but the disintegration of human thought and experience into separate unrelated compartments. . . In so far as the Church nurtures the schizophrenic Christian, the Church herself contributes to the very process of dismemberment which it is her specific business to check and counter. For the Church's function is properly to reconstitute the concept and the reality of the full man, faculties and forces blended and united in the service of God. The Church's mission as the continuing vehicle of divine incarnation is precisely that - to build and rebuild the unified Body made and remade in the image of the Father. The mind of man must be won for God.
