“If purity disposes man to ‘keep his own body with holiness and reverence,’ as we read in 1 Thessalonians 4:3-5, piety as a gift of the Holy Spirit seems to serve purity in a particular way by making the human subject sensitive to the dignity that belongs to the human body in virtue of the mystery of creation and of redemption.”
