This sixth lecture covers an animating theme, concerning blood. Fr. Richard Gilsdorf traces the meaning of blood in Old Testament times with its meaning now in the Eucharist. However, Father Gilsdorf analyzes not only the Old Testament but other ancient writings, like those of Homer, where the sacrificial quality of blood was still strongly understood. This lecture educates it’s listeners on the vast culture of sacrificial blood that existed before Christ and allows one to see the necessity and beauty of Christ’s continued sacrifice on the altar.
