The Catechism of the Catholic Church clearly outlines how the Holy Spirit is represented in names, titles, and symbols:
The proper name of the Holy Spirit
"Holy Spirit" is the proper name of the one whom we adore and glorify with the Father and Son. (691)
Titles of the Holy Spirit
Paragraphs 692-693 highlight many of the titles of the Holy Spirit including "Paraclete," the one used by Jesus.
Symbols of the Holy Spirit
Paragraphs 694-701 highlight the following symbols of the Holy Spirit: water, anointing, fire, cloud and light, the seal, the hand, the finger, and the dove.
Memory Game
Have the students work in pairs to study and remember some of the names, titles, and symbols of the Holy Spirit from these Catechism references. Have them create memory cards to help them remember the definitions. For each term/name, have them create two cards: one with the term, name, or symbol and the other with the definition. When they have finished making the cards, allow them to play a memory game with all the cards faced down on the desk. Students may turn over two cards per turn to match the term with its definition. If they make a match, they may keep the cards. The player with the most cards wins.
