Theodore Beza's A Clear and Simple Treatise Respecting the Lord's Supper (1559) advances a tireless defense of the Reformed perspective on the Lord's Supper, responding chapter by chapter to specific arguments raised against John Calvin by his Lutheran opponent, Joachim Westphal. Beza makes great use of the concept of metonymy, or a figure of speech, in his interpretation of the words of institution, yet he equally champions the position that the Lord's Supper is not a bare symbol and that in it we have true communion with the risen Christ. And like Calvin, Beza refers extensively to the church fathers, especially Augustine, in defense of his position.
