OVERVIEW
Together the three windows represent God's love, demonstrated by gifts which included his son, and his purpose, that all may find salvation through the cross of Christ. These windows are different from the others in the cathedral in being examples of abstract rather than representational art. Abstract art does not attempt to represent external, recognisable reality but seeks to achieve its effect using shapes, forms, colours and textures.

The windows were the gift of Sir Robert Ernest Herdman in memory of his wife Lucy. They were dedicated on Trinity Sunday 1976. The windows were designed by Edward Marr of the Belfast College of Art (now part of the University of Ulster).

THIS WINDOW

This window seeks to depict the Holy Trinity. God the Father is represented by a ball of light. Creation began when God said, 'Let there be light' (Genesis 1:3). Life depends on light and on God. Below the gold light is a dove, symbol of the Holy Spirit, the third person of the Trinity.

Jesus Christ, the second person, is represented by a cross and a crown of thorns. The cross has no figure on it because for Jesus crucifixion was not the end: the empty cross is a symbol of his victory over sin and death.
