Trinity Presbyterian Church began with the evangelical zeal of a distinguished pastor of the First Presbyterian Church, Dr. Russell Stevenson. When some of the young people of the parish came to him for work, he suggested that they begin a Sunday school for the Italians, who were then newly hired to work for GE in Schenectady. From a humble beginning in Sunday school work, Trinity Presbyterian Church has grown.
The Sunday school mission, originally called the San Salvatore Presbyterian mission would grow rapidly reaching an enrollment of 100 by January 1905. Aside from caring for the spiritual needs of its members, the church offered classes in English language and American History to help assimilate new immigrants into citizenship. Eventually, the mission would serve two locations in Schenectady; a “store front” school in the Mount Pleasant section of the city, and what would be understood as the main sanctuary on Jay Street, one block from Schenectady’s City Hall.
