Seton Parish had its origin in the mid-60's when the Diocese purchased the 18 acre tract of land on which the church, Pastoral Activity Center, and rectory now stand.
Father Edward Fairchild was assigned to organize the parish, which started on July 1, 1978. The first Masses and Religious Education Classes were held in the Pickerington Middle School from then until February 1981, when the new church was dedicated by Bishop Edward Herrmann.

Father Stephen Hawkins became Pastor in July 1988, and by 1990, with a growth to over 1000 families, a need to add to our facility became evident. Several hundred parishioners met under the guidance of Bill Brown and Associates on a "Journey to Decision" during the 1991 Lenten Season. A parish consensus was reached to construct a new larger worship space and add additional classroom facilities.

Under the guidance of a central Steering Committee, and over 30 task force groups meeting frequently, all parishioners had an opportunity to contribute input to the endeavor.
The focus of the design was the evolution of the parish character. After worshipping for years in a multipurpose space, the community was starved for a permanent, sacred space. Older members identified with a more traditional and respectful setting for the Mass. Younger members wanted their children to grow up with a sense of the same respect and faith. These desires, coupled with a growing closer to the guidelines for Vatican II, developed the church form sacred and separate from the other parish functions. The Nave is perceived as the central focus coming in either direction on State Route 256. The stone appearance adds permanence, while the stucco and roof forms tie the complex together with the rectory to complete the composition.

The major interior design concept is the fellowship of believers gathering around the altar in a hospitable atmosphere. The sanctuary is connected to the other functions of the parish by a narthex space that promotes fellowship both before and after Mass.

The dedication of the church of Seton Parish on September 13, 1992, by Bishop James Griffin was a celebration of the continuation of God's growth among us.

In 2001, the Parish Activity Center was opened. This facility offers a full gym and stage as well as a kitchen. This facility has become a meeting place not only for the Parish community, but also for the Pickerington community. With continued growth in the Pickerington area, additional educational
