In the church vestibule is its baptismal font, made of white Carrara marble with a pewter upper covering and silver basin.
Inside, a gallery runs around the sides and back on the upper story, supported by clustered columns in a French Gothic style.
It ends near the chancel, creating the illusion of transept arms on either side.
Near the altar the arches are styled in the fashion of the Italian Renaissance.

The pews are of pine painted to look like pine grained to resemble oak, capped with black walnut.
It is complemented by the communion rail, black walnut with oak spindles.
The Stations of the Cross around the side are carved painted reliefs set in wooden frames.
Brown metal plaques, covering the original German text, describe each one.
Around the church are four separate altars, most in white with gilded trim.
Atop one are carved wooden statues of four saints—Isaac Jogues, Elizabeth Ann Seton, John Neumann and Kateri Tekakwitha—all of whom had at least a tangential connection to the church during their lives.

Above the gallery there are statues and paintings of other architectural elements.
Combined they create the impression of a clerestory.
On the ceiling is further trompe l'œil.
