'This commentary on Aquinas's treatise on the Divine Law is a worthy and, indeed, indispensable sequel to the author's prequel, his successful commentary on Aquinas's Treatise on Law, in which the focus was law in general, eternal law, natural law, and human law. The sequel expands into a lucid treatment of the revealed divine law, old and new, in all its complexity. Directed primarily at those who study this demanding and difficult treatise for the first time but also instructive for the seasoned scholar, Budziszewski offers the first English-speaking commentary on the divine law in more than one generation. Clearly organized and lucidly written, this is an invaluable resource for every student of Thomas Aquinas, especially neophytes to Aquinas's thought, be they seminarians, undergraduate and graduate students, or the proverbial layperson who is looking for a reliable guide into Aquinas's teaching on the divine law.' Reinhard Huetter, Ordinarius Academician of the Pontifical Academy of St Thomas Aquinas
