Church Fathers on Matthew 26:26
When the typical Passover was concluded, and He had partaken of the Lamb with His Apostles, He comes to the true paschal sacrament; that, as Melchisedech [marg. note: Gen 14:18], Priest of the most high God, had done in foreshadowing Christ, offering bread and wine, He also should offer the present verity of His Body and Blood.
