The judgment that one forms of the theory and practice of penance in Christian antiquity will be largely determined by the interpretation which one puts upon these two treatises. On Penitence dates from Tertullian's Catholic period, and is a sermon addressed to the faithful on the subject of repentance and forgiveness. On Purity is one of his most violent Montanist treatises. In it he criticizes the policy the church follows in granting pardon to serious sins. +

This volume is a major resource for the interpretation, theology, and practice of communal and individual penitence. It gives teachers, preachers, and serious students of theology an exhaustive source of information and inspiration for renewing the initial call of Jesus to "Repent and believe in the Gospel" (Mark 1:15).

Marriage, Celibacy, and Heresy in Ancient Christianity is the first major study in English of the 'heretic' Jovinian and the Jovinianist controversy. David G. Hunter examines early Christian views on marriage and celibacy in the first three centuries and the development of an anti-heretical tradition. He provides a thorough analysis of the responses of Jovinian's main opponents, including Pope Siricius, Ambrose, Jerome, Pelagius, and Augustine. In the course of his discussion Hunter sheds new light on the origins of Christian asceticism, the rise of clerical celibacy, the development of Marian doctrine, and the formation of 'orthodoxy' and 'heresy' in early Christianity.

"Address to the Christian Nobility of the German Nation" is the first of the three tracts written by Martin Luther in 1520. In this work, he defined for the first time the signature doctrines of the priesthood of all believers and the two kingdoms. After the church made a strong attempt at drawing distinct lines on saying who had authority in the spiritual sphere and its matters. This division of Christians into spheres motivated Luther to write on the "three walls" the "Romanists" created to protect themselves from reform. "Prelude on the Babylonian Captivity of the Church" is a theological treatise, the second of the three major tracts from 1520. In this work Luther examines the seven sacraments of the Catholic Church in the light of his interpretation of the Bible. With regard to the Eucharist, he advocates restoring the cup to the laity, dismisses the Catholic doctrine of Transubstantiation but affirms the real presence of the body and blood of Christ in the Eucharist, and rejects the teaching that the Mass is a sacrifice offered to God. "A Treatise on Christian Liberty" is the third of Luther's major reforming treatises of 1520. It developed the concept that as fully forgiven children of God, Christians are no longer compelled to keep God's law; however, they freely and willingly serve God and their neighbors. Luther also further develops the concept of justification by faith. In the treatise, Luther stated, "A Christian is a perfectly free lord of all, subject to none. A Christian is a perfectly dutiful servant of all, subject to all."

Originally published in 1997, Medieval Liturgy is a unique and interesting collection of nine essays that explores medieval liturgy from three distinct perspectives: historical, liturgical, and theological. The book includes contributions from eminent scholars of the time and discusses the development of 9th to 11th century ordines, the meaning of the Mass in the 12th and 13th centuries, medieval preaching, ordination practices, popular penance practices, marriage rites, the role of music in Eucharistic liturgy, and the relationship between liturgical architectural space and theology.
