Do you think Luther actually had a sound grasp on church history here, or were you just quoting Luther to give his opinion? If you are curious I could provide a reference or two or three from some respected modern scholars that don’t exactly think the likes of Augustine believed in a Real Presence.
Judge for yourself:
bread which you see on the altar is, sanctified by the word of God, the body of Christ; that chalice, or rather what is contained in the chalice, is, sanctified by the word of God, the blood of Christ. {Sermo 227; on p.377}
Christ bore Himself in His hands, when He offered His body saying: “this is my body.” {Enarr. in Ps. 33 Sermo 1, 10; on p.377}
Nobody eats this flesh without previously adoring it. {Enarr. in Ps. 98, 9; on p.387}
[Referring to the sacrifice of Melchizedek (Gen 14:18 ff.)] The sacrifice appeared for the first time there which is now offered to God by Christians throughout the whole world. {City of God, 16, 22; on p.403}
Christ is both the priest, offering Himself, and Himself the Victim. He willed that the sacramental sign of this should be the daily sacrifice of the Church. {Ibid, 10, 20; on p.99}
He took flesh from the flesh of Mary
. . . and gave us the same flesh to be eaten unto salvation . . . we do sin by not adoring. {Explanations of the Psalms, 98, 9; on p.20}
Not all bread, but only that which receives the blessing of Christ, becomes Christ’s body. {Ibid., 234, 2; on p.31}
What you see is the bread and the chalice . . . But what your faith obliges you to accept is that the bread is the Body of Christ and the chalice the Blood of Christ. {Ibid., 272; on p.32}
Not only is no one forbidden to take as food the Blood of this Sacrifice, rather, all who wish to possess life are exhorted to drink thereof. {Questions of the Hepateuch, 3, 57; on p.134}
The Sacrifice of our times is the Body and Blood of the Priest Himself . . . Recognize then in the Bread what hung upon the tree; in the chalice what flowed from His side. {Sermo iii. 1-2; on p.62}
The Blood they had previously shed they afterwards drank. {Mai 26, 2; 86, 3; on p.64}
Eat Christ, then; though eaten He yet lives, for when slain He rose from the dead. Nor do we divide Him into parts when we eat Him: though indeed this is done in the Sacrament, as the faithful well know when they eat the Flesh of Christ, for each receives his part, hence are those parts called graces. Yet though thus eaten in parts He remains whole and entire; eaten in parts in the Sacrament, He remains whole and entire in Heaven. {Mai 129, 1; cf. Sermon 131; on p.65}
Out of hatred of Christ the crowd there shed Cyprian’s blood, but today a reverential multitude gathers to drink the Blood of Christ . . . this altar . . . whereon a Sacrifice is offered to God . . . {Sermo 310, 2; cf. City of God, 8, 27, 1; on p.65}
He took into His hands what the faithful understand; He in some sort bore Himself when He said: This is My Body. {Enarr. 1, 10 on Ps. 33; on p.65}
The very first heresy was formulated when men said: “this saying is hard and who can bear it [Jn 6:60]?” {Enarr. 1, 23 on Ps. 54; on p.66}
Thou art the Priest, Thou the Victim, Thou the Offerer, Thou the Offering. {Enarr. 1, 6 on Ps. 44; on p.66}
