Chapter 1, Part 2 - The Eucharistic Sacrifice (p. 14)
In the Middle Ages, until the early 13th century, the idea of the mass as a sacrifice was only rejected by those who rejected the entire mass. This view of the priesthood and sacrifice was handed down from the earliest period of Christianity and was readily understood by people from either a pagan or Jewish background. The people would bring offerings which were then presented to the Lord. Where Sasse views the Church going wrong is in laying the gifts, including bread and wine, on the altar, suggesting to some that the church is offering the body and blood of Christ to God. This view has taken root in the Roman Liturgical Movement (p. 16) and has not basis in Scripture. This serves as an important part of the background of the Reformation.
