In the book, How to Teach The Catechism to Children, by Joyce M. Horton, there are some helpful discussion questions / topics you can use during the Truth Made Known time.
Q. What are the two sacraments? A. Baptism and the Lord’s supper
A sacrament is an outward, holy sign or seal begun by Christ which testifies to the application of the covenant of grace to believers. (And outward sign of an inward act).
The Lord’s Supper (also known as Communion) is the passing and partaking of bread and wine (grape juice) in church. It’s a special time at church when we join together to remember how Jesus sacrificed for us by dying on the cross.
Communion is also called the Lord’s Supper because we eat together at church just like Jesus did with His disciples the night before He died.
Jesus told us we should continue to eat this special meal of bread and wine (or grape juice) to always remember Him. The bread reminds us of Jesus’ body, and the wine reminds us of His blood.
Jesus gave His body and His blood away when He died for our sins. He did this to take the punishment we all deserve so that we won’t have to be punished when we die but will go to Heaven with Him.
The Lord’s Supper is symbolic and not literal. We are not literally drinking Jesus’ blood and eating His body.
Baptism is a visual picture of a person's relationship with Christ. It shows others that our old way of life is gone and now we are a new creation in Christ. We’ve been “washed” clean. 2 Corinthians 5:17 says, “If anyone belongs to Christ, then he is made new. The old things have gone; everything is made new!”
Baptism does not really wash away our sins. Jesus is the only one who can take away our sins.
Baptism is a symbol of what Jesus has already done for us. Because Jesus died and rose again, when God the Father looks at us, He doesn’t see our sin. He is looking at our hearts through the blood of Jesus.
Think about a wedding ring. Does a wedding ring make someone married? No. You must go through a wedding ceremony and sign a legal document to be married. A wedding ring is a symbol, it shows people that they are married. If a married person takes off their ring are they still married?
Baptism is a symbol. It shows others that our lives are new and different because we follow Jesus.
Scripture Reference:
Colossians 2:11-12 - In him also you were circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ, 12 having been buried with him in baptism, in which you were also raised with him through faith in the powerful working of God, who raised him from the dead.
Q: Why did Christ appoint these sacraments? A: To distinguish his people from the world, and to comfort and strengthen them.
To be distinguished means that we are set apart - we are different. These are ways the Christian shows the world that we are different. We are set apart from the world.
Comfort means to make one feel better - like a mother comforts her child when they are hurt. The Lord’s Supper and baptism are given to us as a comfort. They clinch or seal. It makes us know that we are children of God.
Baptism and the Lord’s Supper (also known as Communion) help us when we are down; they remind us that we are God’s children and that we are growing on the nourishment of Christ; and they strengthen us.
Scripture Reference:
Titus 3:5 - he saved us, not because of works done by us in righteousness, but according to his own mercy, by the washing of regeneration and renewal of the Holy Spirit,
1 Corinthians 11:23-26 - For I received from the Lord what I also delivered to you, that the Lord Jesus on the night when he was betrayed took bread, 24 and when he had given thanks, he broke it, and said, “This is my body, which is for[f] you. Do this in remembrance of me.”[g] 25 In the same way also he took the cup, after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.” 26 For as often as you eat this bread and drink the cup, you proclaim the Lord's death until he comes.
