In this last work of Vermigli's distinguished career as a theologian, he uses a dialogue to discuss the disagreement among Christians about the Eucharist and Christ's presence in the Lord's Supper. Peter Martyr Vermigli (1499-1562) is considered to be one of the most important Italian reformers of the early modern period. Martyr is the subject of renewed interest for historical and theological scholars. The Peter Martyr Library, a series of critical English translations of the chief works of Peter Martyr Vermigli, allows his own words in context to speak for themselves.
