Boethius’ life and works form the bridge between classical philosophy and medieval
theology. This collection contains five theological treatises: “The Trinity is One God Not
Three Gods,” “Whether Father, Son, and Holy Spirit may be Substantially Predicated of
the Divinity,” “How Substances can be Good in Virtue of their Existence Without Being
Absolute Goods,” “On the Catholic Faith,” and “Against Eutyches and Nestorius.” These
essays serve to defend orthodox Christian doctrine against various heresies, particularly
Arianism and Nestorianism. Boethius articulates his views carefully and philosophically.
Consequently, philosophers often read the treatises as supplements to Boethius’ classic
work, The Consolation of Philosophy.
