Trinity Sunday – Sunday School

This Sunday we celebrate the idea of The Trinity – God the Father, Son and Holy Spirit.
The word Tri is used as a prefix (a word, letter or number used in front of a word to make a new word) to mean THREE. How many other words can you think of that start with Tri? I can think of five (no, not three!)

What is the Trinity?

The idea of The Trinity is quite a hard one to grasp. God is three things in one: The Father, The Son and the Holy Spirit. But how can that be? How can three separate things be just one thing? It’s something lots of people struggle to understand and, as with other things in life, sometimes we just have to believe and have Faith without fully understanding; so many things about God are beyond our understanding.

However, I’ve found it really useful to think of the Trinity in this way – think of water. How many different forms can water take?
We can make ice from water by freezing it, steam from water by boiling it, ice melts to become water and steam turns back into water by condensation. They are connected, from the same origin but also have their own distinctive nature.
Why not make water into ice and steam and back again.

Trinity Sunday hymns

We sing lots of wonderful songs on Trinity Sunday, which celebrate God in three persons. Look up the words for them, I wonder if you can remember the tunes?

Firmly I believe and truly (John Henry Newman)

Holy Holy Holy (Reginald Heber)

Lead Us Heavenly Father Lead Us (James Edmeston)


Make a tabletop spinner. Cut a circle from cardboard and colour in three segments with different colours. Cut a slot in the middle for a one pence coin. Push in so it’s halfway through. You can then spin it on a table top and see the colours merging into one colour. Try different patterns and colours. I’ve made a template you can use if you need it. You can print it and glue onto a piece of card.


This beautiful verse by Thomas Ken (1674) can be sung as well as spoken. You can hear the tune here:

You can even sing it in a round – maybe even with three people!

Praise God from whom all blessings flow.
Praise Him all creatures here below.
Praise Him above ye heavenly hosts.
Praise Father Son and Holy Ghost.
