According to Thomas Aquinas, the Eucharist is meant to build up the unity of the church. This desired ecclesial unity is, however, not often given adequate treatment. In Speaking with Aquinas, David Farina Turnbloom seeks to describe the relationship between the celebration of the Eucharist and the unity of the church. By examining Aquinas's treatment of grace and virtues, this book allows the reader to understand Aquinas's eucharistic theology within the context of the spiritual life of the church. In the end, Turnbloom retrieves a Thomistic theology of the Eucharist that arises from Aquinas's concern for the virtuous life of the church, rather than a eucharistic theology that too narrowly focuses on theories of transubstantiation.
