““shedding of blood for sacrificial purposes,— the one real and physical, the other sacramental and mystical. The former took place in the bloody sacrifices of the Old Testament, and also in the Crucifixion, when the Precious Blood of our Saviour actually flowed from His veins and was separated from the Body. When we speak of the sacramental shedding of blood (effusio sanguinis sacra-mentalis s. mystica) we mean that Christ offers His Blood for us in so far as it is represented as mystically separated from His Body. This mystic slaying of the Eucharistic Lamb is an imitation and sacramental representation of the physical killing on the Cross. It is in this sense that we must understand the famous saying that the double Consecration is a mystic sword which separates the Blood of Christ from His Body and thereby graphically repre sents His death on the Cross.””
