Behold the Lamb of God...

In Jewish custom the lambs were meant to be killed and eaten. Since Catholicism is the fullfilment of Judaism, the Host is consecrated by the Priest, (in persona Christi, Christ himself, through the priest consecrates this host)and we are called to the Eucharistic sacrifice meal, to eat, gnaw, chew, masticate the Lamb of God, as Jesus said, as He told us to do. He offered not a symbol of his flesh, but he offered His Flesh, His Body, His Blood, to be eaten until the end of time, when, those who have persevered to the end, will enjoy eternal life with Him.
