Yellow symbolizes the Holy Spirit. Haufschild states that the windows contain a lot of white glass as an expression of opening, the hope and freedom for the refugees and a clear experience of the inside and outside as the same time. He also said that he feels fortunate to have had a studio inside the church. "I walked through every day in all kinds of light conditions and really got the chance to understand the space."
Haufschild's
windows are intentionally subtle. He dislikes windows that are filled
with a multitude of symbols which overloads the space and diminishes
the design creating what he calls "symbol soup." For example in the
West window the center window has the colour yellow, symbolizing the
Holy Spirit, while the smaller two windows have a hint of blue painted
looking somewhat like clouds or a mist. There are no white doves, which
are so often used to reference the Holy Spirit instead subtle colour is
used.
Beside the Trinity windows and the lower windows are windows containing the Lord's Prayer in multiple languages published in 1685 by Latvian Lutheran Pastor Janis Reiters. (Pamphlet 1)
