A short extract from one book used for teaching children:
“… A little while before His death on the cross, Jesus gathered His friends around Him one evening for a last meal together. He said: For a long time, I have thought about having this last meal with you. Then He stood up, took the bread which was on the table, blessed it, and said: Take and eat this: This is My Body. Then He took the wine and said:
Take and drink this: This is My Blood, which I am going to shed for you. Then the friends of Jesus remembered the promise they had never understood. The promise was: I am the Bread that came down from heaven. Whoever eats this Bread will always be with God. The Bread that I give is My Body.
This is the Food for our souls that our Father gives us every time we receive Holy Communion. He gives His Son to us so that Jesus can work in us, and make us true children of God. Holy Communion will make us more like Jesus Christ. Jesus will fill us with His life and love. When we have His love-life in us, we try to act towards other people as He did. We try to love the people in our family, our school, our street, in the way that Jesus showed us when He was on earth.
He is our way to God, and will teach us to love as God wants us to. …”

"THE MASS – A GIFT TO OUR HEAVENLY FATHER
When we go to Mass we offer a Sacrifice to God. We do not offer lambs or fruit any more. Jesus has given us a much greater Gift to our Heavenly Father. This Gift is Himself. He planned a way for us at the Last Supper.
After the prayers and readings, some bread and wine are brought to the altar, as a gift from us to show God that we want to give ourselves to Him. Something wonderful happens to our gift before it is offered to God.
At the Consecration the priest says the words that Jesus said at the Last Supper, and the bread and wine are changed into our Lord Himself.
Jesus offers Himself to the Heavenly Father, and we join with the priest in offering Him, too, just as if we had been on Calvary with Him.
This is our great Sacrifice, too."
