First Lutheran Church is of special artistic interest because of the unity of its artistic embellishments. The extraordinary pieces of ecclesiastical art (four above all: the mosaic of the Presentation above the altar, the tabernacle, the Good Shepherd window, and the free-standing altar) are each of great individual interest, beauty, and power. These pieces, however function not just as separate works but are parts of a whole fabric of intentional design, with echoes of and illusions to each other that in their interaction give a remarkable unity and force to the individual works and to the building which houses them.
