The parish was founded in 1855. In 1854, Mrs. Mathilda Dallas Wilkins, a prominent East Liberty resident and the wife of Judge William Wilkins, requested unsuccessfully of Bishop Alonzo Potter, the third bishop of the Diocese of Pennsylvania, that an Episcopal parish be founded in East Liberty. Not to be deterred, Mrs. Wilkins spearheaded an organizational meeting for a new parish. The Rev. William Paddock agreed to lead regular services for a new congregation on the condition that an appropriate worship site was found. Rev. Paddock, along with thirteen others, then incorporated Calvary Episcopal Church, subsequently adopting a charter and by-laws. The first services of the new Calvary congregation were held in January 1855 in space rented from a German Lutheran Church. The building was located in an alley between Collins and Sheridan avenues in the Village of East Liberty. Within a year, Calvary bought this first building.
