On July 1, 2016, the Most Reverend Peter A. Libasci, D.D., Bishop of Manchester, New Hampshire created a new Personal Parish "to serve those faithful who, out of sincere attachment to the Latin liturgical tradition, desire to celebrate the Rites of the Church exclusively in accord with the typical edition of the liturgical books by Saint John XXIII in 1962."
He entrusted the care of the parish to the Priestly Fraternity of St. Peter, a Society of Apostolic Life founded at Rome in 1988.
The new Catholic parish is located at St. Stanislaus Church, formerly a Polish Parish (built 1908) which was merged with St. Aloyisius Gonzagua Parish in 2002. The new Personal Parish of St. Stanislaus is a full parish in the Diocese of Manchester offering all Masses and Sacraments in the Traditional rites.
The first Sunday Mass was offered on August 7, 2016.
