In “Sacred Art Every Catholic Should Know,” author Jem Sullivan, a catechetics professor, shares her knowledge of Christian masterpieces. The book reminds us that many of the world’s most admired and treasured artistic works are Christian in theme, origin and location – and many of those depict or allude to the Eucharist. Two such masterpieces in this new release from TAN Books are Raphael’s “Disputation of the Most Holy Sacrament” and Leonardo da Vinci’s “The Last Supper.”
