Jesus tried multiple times to teach his diciples about his body and blood.
Fruit of the vine and work of human hands, then you will join me in Heaven
Jesus is the living Bread of God, who acts through the priest.
I will give myself up for you, because I love you
Scourging at the Pillar.
Jesus is the Sacrificial Lamb of God. He gave himself up so we could recieve his spiritual body. That way we can join him in heaven. He is the drink and bread that will always fill us, no matter how great a feast.
His body changed into spiritual form.
Which the Holy Spirit comes to make Holy. Therefore we are consuming the risen body.
His bones were not broken, unlike the two at his side.
Which unites us with the Church on Earth and in Heaven.
