When we praise a great work of art or a wonderful piece of music, we are automatically praising the person who made or composed it. And this is exactly what happens when we honour the saints. We are honouring God by Whose grace alone they are what they are (1 Corinthians 15, 10). That is why scripture says: God is glorious in His saints (Psalm 68, 35, LXX). Honouring them does not detract from His honour: rather it leads us to honour Him all the more in those who are His workmanship (Ephesians 2, 10).
