The introit was part of a join project with Kathinka de Ruiter for the birthday of our minister, Margreet Klokke, which included compositions by Kathinka.
Dominus Illumatio Mea is Psalm 27 in the Vulgate, and Psalm 26 for the Leidse Binnenstadsgemeente:
The Lord is my light and my salvation; whom shall I fear? The Lord is the strength of my life; of whom shall I be afraid?
When the wicked, even mine enemies and my foes, came upon me to eat up my flesh, they stumbled and fell.
Though an host should encamp against me, my heart shall not fear: though war should rise against me, in this will I be confident.
