Teach Kids About Transubstantiation- An Object Lesson

We’re working on helping our kids understand the true presence in the Eucharist as First Communion time approaches for our oldest. To understand the true presence of Jesus in the Eucharist, you have to explain transubstantiation. I’ve been loving the idea of trying out some object lessons for Catholic kids at home, and I wanted to share one of them with you today.

explaining the true presence in the Eucharist to kids

Transubstantiation is the process of the bread and wine truly changing in substance into the Body and Blood of Jesus. Although our outside senses (taste, touch, smell, etc) still see it as bread and wine, it is actually the Body and Blood of Christ. This object lesson helps to understand the concept of transubstantiation.

You start with a ball. We used this spiky red ball. Then, I painted it blue. (I made this easy by putting paint on a paper plate and rolling it around with my spagetti-picker-upper-thingies.)

You talk to the kids and ask questions like:

  • What has changed about the ball? (the color)
  • Is it a different ball now? (no)
  • Did it actually change? (no)
  • What is different about it? (the way it looks)

You make the point that it’s exactly the same ball, but it looks different. Then you tell them that the Eucharist is exactly the opposite. When the host is turned into the body of Christ, it doesn’t look different, smell different, or even taste different- yet what it is has completely changed. It’s the opposite of what happened to the ball. You can explain it from the perspective of the bread, and then also the wine.

Once you feel like you’ve made your point, you can wash the wet paint back off of your ball and return it to your toy box. Our ball actually washed off quite quickly.

  1. Thanks for the great ideas. They are helpful with my religious ed kindergarten. May I ask what kind of paint did you use?

  2. I love your blog! But I must disagree with this particular lesson. It is confusing. An ‘object lesson’ is something that serves as a practical example of a principle or abstract idea,
    “When the host is turned into the body of Christ, it doesn’t look different, smell different, or even taste different- yet what it is has completely changed. It’s the opposite of what happened to the ball. You don’t use O.L. to teach opposites. The conceptionalization of transubstantiation is a difficult thought for adults to absorb, that is why it is an idea left more to faith than thought. Perhaps exploring three extraordinary miracles of the Eucharist – Santarem, Amsterdam & Offida or sharing a video ( http://www.youtube.com/watch?v=jqsRDD6kXWY ) will get them thinking.

  3. Maybe for the smallest ones we should start with a box with a hole to put the hand inside and place an objetc there. With the eyes covered they could start playing this game, trying to see without the eyes, using other senses. After a time playing start questions like: what’s the color you think the object you are holding has? Things like this could be fun to the 5-6 years old… I’ll try.

    Thanks for always sharing!

  4. This is great! Can’t wait to do it with my kids at home and in my faith formation class. When I was working with the youth group, there was a youth leader who used CDs as an analogy. It looks like a disc but after you burn it, there is something more to it…music…even though you can’t see it. I love your ball idea though. It’s great for early childhood! Cd’s might be a little more difficult.

  5. Simply a brilliant way to explain!

  6. I was writing this into my lesson plans, but on further thought I tend to agree that young kids might find this confusing since it is such a vivid image, and remember the “wrong” lesson. I was thinking on this and another idea occurred to me. I think I might do an object lesson with a class of water, and some liquid sugar (simple syrup, which is clear). The water does not change its appearance with the addition of the simple syrup, but it changes! This has the same problem as your image in that we have to back track and explain that while the TASTE of the water changes, that does NOT happen with the Host, but it comes a little closer since it does illustrate a change we cannot see (and we can refer to the “sweetness” of the Lord.) It occurred to me to do the same thing but add liquid vitamins…..but, that has the same issue as the thing we’re trying to explain – they have to take it on trust!

  7. Michaele says:

    Have you considered using eggs? After the egg is boiled, the shell and shaped are the same, but it changes “inside.” Just looking at the outside of two eggs, you can’t tell which one is boiled and which one is not. Kids can see the water boiling and eggs in the pan but they can’t “see” the change on the inside. Kids can see and hear the priest saying the prayers, but they can’t see the change. This is what I am going to use to explain to my class.
