Written in 1561, Martin Chemnitz's "Repetition of the Sound Doctrine Concerning the True Presence of the Body and Blood of the Lord in the Supper” provided a thorough examination of the teaching of Holy Scripture concerning the Sacrament of the Altar. During the 1560s, controversies raged within the Evangelical Lutheran Church on this topic, but Chemnitz and other faithful teachers of the Church brought unity in the divine Truth and helped to guide the Church toward the clear confession contained in the Book of Concord (1580).Chemnitz provides a comprehensive presentation of the teachings of Holy Scripture, and demonstrates that the doctrine of the Church Fathers concerning the Lord's Supper is most faithfully upheld among Evangelical Lutherans. Chemnitz offers a summary of the controversies concerning the Lord's Supper which have arisen since the second century, and presents a thorough examination of Sacramental theology in light of orthodox Christology.
