This is a fascinating study from Kevin Duffy. … Unlike many studies of this genre, it is at all times thought provoking and readable.

The volume is a pleasing book product, stimulating, easy to consult and the sort of book that might be retained as a personal possession and re-read from time to time. It contains well-honed thoughts that may grow on a reader in different moments of life's seasons.

Ephemerides Liturgicae

The joy of sunrise, the melancholy of sunset, the Sun which gives us light, and warmth, and life. We rarely do anything without some reference to it - our local star. Yet for much of Christian history our references in a religious context have been complex: Jesus is the Sun of Justice who visits us like the rising Sun, and we have a solar liturgical year, but we are dismissive of 'solar cults' and 'Sun worship' - yet it is by the visible that we speak of the invisible. At last, we now have a book that addresses the whole topic and does so thoroughly.

A timely and pioneering study retrieving the symbols of light and sun to counterbalance a tradition often preoccupied by darkness and cloud and tracing their implications for Christology, spirituality, and liturgy.

In his fascinating study of sun symbolism, Kevin Duffy has created something truly fresh, informative, and-dare we say it-illuminating! Tracing the history of the symbols of sun and light and their interplay with darkness reveals a rich symbol of the divine presence, rooted in the Scriptures, reflected in aspects of our tradition, downplayed for too long a time, and now ready for a vigorous revival. Theologians, spiritual writers, poets, and everyday Christians will find this a splendid and inspiring work.

Kevin Duffy's thorough and painstaking research lays a solid foundation for the retrieval and development of solar metaphors and the symbolism of light in contemporary theology. Such theological language would not only assist Christian thought in addressing the climate crisis of our time, but to reinscribe Christ as the "Sun of Justice.
