How It All Began
The idea of the Holy Trinity has been part of Christian teaching since the early church. But Trinity Sunday became a special celebration around the 10th century. It was made official by Pope John XXII in the 14th century.

The Concept of the Holy Trinity in Christianity
The Holy Trinity can sound confusing, but it helps us understand how God works.
What Does “Trinity” Mean?
The word “Trinity” means three-in-one. In Christianity, it means God is one being who exists as three persons — the Father, the Son, and the Holy Spirit.
An Example to Understand
Think of water. It can be ice, liquid, or steam. But it’s still the same water. The Trinity is similar. God shows up in three ways, but He’s still one God.
Why It Matters
The Trinity shows how God is with us:
- The Father created the world.
- The Son, Jesus, saves us.
- The Holy Spirit helps and guides us every day.
📖 “Therefore go and make disciples… baptizing them in the name of the Father and of the Son and of the Holy Spirit.” — Matthew 28:19 (NIV)
