I believe in the Holy Spirit
The Holy Spirit is God, the third Person of the Trinity, sent to be our helper and to make the Church holy. He prays in us and shows His presence in real, visible fruit.

The third part of the Creed begins. To believe in the Holy Spirit is to profess that He is one of the Persons of the Trinity, fully God, worshipped and glorified together with the Father and the Son (CCC 685). He is not a force, an energy or a mood. He is Someone. That is why Christians say He, not it.
Jesus gave Him a name: Paraclete, literally one called to your side. The word covers advocate, helper and consoler (CCC 692). Jesus also called Him the Spirit of truth, who would teach the apostles all truth. Scripture gives other titles too: Spirit of the promise, Spirit of adoption, Spirit of Christ, Spirit of the Lord (CCC 693).
Because we cannot see the Spirit, Scripture uses images. Water, for new birth in Baptism. Anointing with oil, for strength and mission. Fire, for His transforming energy. The cloud and light. The laying on of hands. The dove that came down on Jesus at His baptism (CCC 694-701). The Church still uses many of these signs in her sacraments.
The Spirit was at work long before Pentecost. He hovered over the waters at creation, spoke through the prophets, and overshadowed Mary (CCC 702). But at Pentecost, fifty days after Easter, He was poured out on the Church in a new way, and the Trinity was fully revealed (CCC 731-732). Ever since, He builds, animates and makes holy the Church (CCC 747).
As the Nicene Creed is prayed in the West, it says the Spirit proceeds from the Father and the Son. The Eastern Churches say from the Father, and through the Son. The Catholic Church understands both traditions as expressing the same faith from different angles, when rightly understood (CCC 246-248).
What does the Spirit do in you? He prays in you when you do not know how to pray (CCC 741). He gives seven gifts: wisdom, understanding, counsel, fortitude, knowledge, piety and fear of the Lord (CCC 1831). And He produces fruit you can actually see. The tradition counts twelve, following the old Latin Bible that the Douay-Rheims translates: charity, joy, peace, patience, benignity, goodness, longanimity, mildness, faith, modesty, continency and chastity (CCC 1832).
Key points
- The Holy Spirit is a divine Person, worshipped and glorified with the Father and the Son.
- Jesus called Him the Paraclete, the helper and advocate at our side, and the Spirit of truth.
- He was poured out at Pentecost and now builds and sanctifies the Church.
- He prays in us, gives seven gifts, and produces visible fruit in our lives.
The Word of God
But when he, the Spirit of truth, is come, he will teach you all truth. For he shall not speak of himself; but what things soever he shall hear, he shall speak; and the things that are to come, he shall shew you.
Likewise the Spirit also helpeth our infirmity. For we know not what we should pray for as we ought; but the Spirit himself asketh for us with unspeakable groanings.
But the fruit of the Spirit is, charity, joy, peace, patience, benignity, goodness, longanimity, Mildness, faith, modesty, continency, chastity. Against such there is no law.

For catechists: a one hour class plan
Goal. The group should understand that the Holy Spirit is a divine Person who builds and sanctifies the Church, and take to heart that He prays in us and bears visible fruit in their lives.
Opener. Ask: "If you had to describe the Holy Spirit to a child, what picture would you use?" Collect a few: a dove, fire, wind, breath. Note that the Bible uses all of these.
Discussion questions
- Why does it matter that the Holy Spirit is a Person and not a force? [We can pray to Him, be guided by Him. Worship and glory with the Father and the Son.]
- Paraclete means helper and advocate at our side. When have you needed an advocate? [Connect to the Spirit's help in hard moments.]
- Romans 8:26 says the Spirit prays in us when we do not know how to pray. What comfort does that give? [Very helpful to people who feel they pray badly or not at all.]
- Which of the fruits of the Spirit (Galatians 5:22-23) do you most need right now? [Make it personal and honest.]
Activity. Hand out the list of the twelve fruits and the seven gifts of the Holy Spirit. Each person circles the fruit they most lack (3 minutes). In pairs (8 minutes), each shares their fruit and the partner prays a short prayer for them aloud or silently: Holy Spirit, grow this fruit in my friend.
Closing prayer. Come, Holy Spirit, Helper and Spirit of truth. Pray in us when we have no words. Make the Church holy, and make each of us holy too. Grow Your fruit in our lives, especially the fruit each of us needs most this week. Amen.
Timing. Opening prayer 5 min, opener 5 min, read the lesson together 15 min, discussion 18 min, activity 12 min, closing 5 min.
