73 To the unbloody gift of Himself under the appearance of bread and wine our Savior Jesus Christ wished to join, as the chief proof of His deep and infinite love, the bloody sacrifice of the Cross. By this manner of acting He gave an example of His supreme charity, which He had proposed to His disciples as the highest point of love in these words: "Greater love than this no man hath, that a man lay down his life for his friends."(75)
