The interior had a touch of Broadway, though, at the time, that was in the future. Embury enlisted Lucinda Goldsborough Ballard and her cousin, Jean Cotton, to paint the murals on the interior walls of the church. Ballard had just finished her art studies at Fontainebleau, France and the Sorbonne in Paris. She was the daughter of Anna Girault Farrar Goldsborough, a friend of Embry's and a political cartoonist for the New Orleans Times-Picayune. As the murals took shape, the pastor, Rev. Torrance Phelps, began to get complaints from some church members that the artwork was too "Pope-ish." He came to Ballard, and she asked him what he wanted for the ten side panels. He asked her to do the virtues. She replied that she thought there were only three. He then gave her a list of what he considered 10 virtues, saying, "That way I'll have enough for about 40 sermons." Ballard went on to become one of the leading set and costume designers for Broadway and Hollywood with productions such as I Remember Mama, The Glass Menagerie, Annie Get Your Gun, Street Scene, The Fourposter, Cat on a Hot Tin Roof. She retired on Broadway after designing The Sound of Music.
In 1971, the church purchased the former YMCA property to the immediate north, which allowed for the addition of a thirty-place parking lot and a north entrance to the church. To replace a sunken garden facing Academy Street, which had been removed in 1959 to make way for remodeling and the addition to the parish building, the brick walls of the new parking lot were lined with memorial trees and gardens.
Outreach efforts by the church over the years have included, in addition to the stance against slavery, monthly birthday parties at the then Kalamazoo State Hospital, resettling of freedom-loving refugees beginning in 1951, which has continued, and missionary work overseas.
