Andrey- Abbot Suger

Abbot Suger believed in the idea of “divine luminosity” noted earlier by a Greek philosopher. The idea essentially stated that light, specifically light that shined through stained glass windows in churches, was from God & had the power to purify individuals. Is this true? Could this idea parallel the action of baptism, where instead of light, water is used to purify individuals and symbolize a renewal? The use of earthly elements seems to be a common theme to symbolize sacredness.
