I’m not sure that this is exactly what you need, but there’s what I did…A couple of weeks ago, I taught a lesson on the Eucharist to my CCD class. Before class, I set a table as if for a “celebration”…tablecloth, lit candles, beautiful china, decorations, soft music, baskets of small loaves of bread, a Bible placed on either end…I started out the lesson in a different room talking about the meaning of the word “Eucharist” (Thanksgiving) and had arranged beforehand for a student to knock on our door with an “invitation” to come to a celebration. Being all dorky and excited about the celebration, I had the kids make their way down the hall, stopped to wash hands and then were met at the big room with two other students as greeters (“Welcome to our party!” Thanks for coming!"). The students sat down at the table and we started talking about what they had seen/heard/noticed at our celebration. Then, acting dumb, I asked, “Where else do we see these things? Candles, water, music, decorations, people greeting us, etc.” and luckily, the kids got it - then, equated the Liturgy of the Word with the stories we hear at family gatherings and then I started on the Liturgy of the Eucharist…I read the story of the Last Supper (Luke 22: 14-20), emphasizing the “This IS my body” part. He didn’t say, “This REPRESENTS my body”, but “This IS my body.” I then read to them John 6: 35 “I am the bread of life…” - making the connection between sharing bread as in the Last Supper and the fact the Jesus IS the “bread”. Followed that with more in John 6, verses 53 - 56 (Whoever eats my flesh and drinks my blood has eternal life). I kept returning to the connection between Jesus and bread and that we must take the body of Christ (under the appearance of bread) in order to be spiritually nourished, just as we need food to be physically nourished. I also talked about our belief in transubstantiation being a mystery and a miracle…that we don’t have to actually “see” something with our eyes to believe it’s really there. (Do we have to “see” the wind to know it’s there?) I got really excited as I was teaching this lesson and I’m sure that the students think I’m a huge dork, but if it plants the seed in them for believing, I’m okay with that!
Hope this helps. Good Luck!
