If you're looking for a change of pace in your Confirmation class, consider trying this "foldable" activity which stresses how the Confirmandi will be sealed with the Holy Spirit.
Step 1) Discuss the meaning of seals. If possible, pull up an image search on various seals.
Step 2) Explain to the kids that when they are confirmed that they will be sealed with the Holy Spirit, a seal that won't be visible to the human eye, but will indeed always be visible to God.
Step 3) Give each student a square piece of paper and have them fold the corners to the center.
Step 4) Have the students write one of the following phrases on each triangular flap:
Be Sealed ~ With the Gift ~ of the ~ Holy Spirit.
Let the students know that these are the words that the bishop will say to them as they are confirmed.
Step 5) On the inside of each flap, have the students write how seals were used in the Bible ...
Rulers often had seals, sometimes on a "signet ring." Gen. 41:42
God set a seal on Jesus. John 6:27
Christians are sealed through the Holy Spirit. Eph. 1:13
Having the seal of God offers protection. Rev. 9:4
Step 6) As a class, look up and read these four seal-related verses.
Step 7) In the center square section, have the students design a seal that they would like to represent themselves as they prepare for Confirmation. Have them select from some traditional Christian symbols.
Step 8) Allow the students to decorate any other part of their foldable, preferably with Christian symbols.
