St. Peter's began with five families and was designated as a Mission in 1876. Services were held in private homes and public offices for the first 17 years. The Mission was elevated to Parish status in 1890.

The first Church building was completed in 1893 on land donated by Dr. G. A. Foote. The original wood frame building was replaced in 1926 with a gothic style brick structure. A fire destroyed the Rectory in November 1959. In April the following year, the Church was demolished by fire. All of the treasures accumulated over the past 84 years were lost.

As the clean-up effort from the 1960 fire ensued a remarkable discovery was made. The Tabernacle was found under the remains of the Altar, it's door sealed from the intense heat. Vic Gill spent the next year scraping and cleaning the Tabernacle. When he finally was able to open the door an even more remarkable discovery was made. The Ciborium was intact; the lace cloth and consecrated bread were still inside with no visible signs of damage.

The first services after the fire were held in a funeral home. Soon after the fire, a five bedroom home located at College and Foote was purchased from the Wilcox family and served as the Church and Parish Hall. It was later named St. Mark's House. The new Church was dedicated in October 1961.

Numerous memorials were made to enhance the new structure including a custom pipe organ from Germany. Before the instrument reached it's destination, saltwater from a storm at sea damaged the pipes. They were rebuilt and eventually the organ was installed.

St. Mark's House was destroyed by fire in 1970. The present Parish Hall, "Sieben's House", was dedicated in 1972. It was named for Janet Siebens, who dedicated much time and effort to the construction. Mrs. Siebens is known for her statement to Father Coggin after the 1970 fire, "St. Peter's is used to this. We will just have to make more fruitcakes!"
