The stained glass windows in the sanctuary were crafted in 1914 by the St. Joseph Glass Works Company. Their craftsmen faithfully reproduced illustrations from European artists published in religious literature of the time without paying royalties. While some windows feature religious symbols, sixteen display reproductions of original paintings, including six large scenes on the front walls and smaller scenes on the back and side walls. These windows will be featured in an upcoming book by photographer David Graves highlighting stained glass in similar churches.
