Abstract

Moral transformation is the process by which a person grows in holiness. The grace of the Holy Spirit enables this growth. This article explores how the notion of ‘prudence of the Spirit’ in Aquinas’s commentary on Romans can help to further elaborate the concept of moral transformation. It does so by first presenting this transformation as a human process. Second, the article presents an in-depth interpretation of Aquinas’s commentary on Romans 8:14: ‘those who are led by the Spirit of God are children of God’. Here, special attention will be given to the proper character of the prudence the Holy Spirit forms in believers. The concluding discussion draws lessons from our reading of the commentary and related texts. This reinforces the conviction that grace enables freedom and will help us to find proper metaphors for speaking of the transformative work of the Holy Spirit.
