Before North Dakota became a state in 1889, immigrants from Europe and Russia settled small rural communities on the rolling hills of the prairie.  These hard-working men and women brought with them a deep faith which necessitated building a place to worship their God. Saints Peter and Paul Catholic Church at Fallon was established in 1908. St. Lawrence parish was a mission of Sts. Peter & Paul until 1912. As the number of paristhioners at at both parishes grew, Bishop Vincent de Paul Wehrle, OSB, established St. Lawrence as a parish in 1912. Thirteen original families were the foundation of the new faith community. Fr. Joseph Neibler baptized the first child, Florence Woll, in the new church on March 18, 1913. 
The original church building cost $4,000.00 and could accommodate about fifty families. Fr. John Selder became the first resident pastor in 1922.
Fr. Joseph Pottgens became pastor in 1941. Starting in 1948, under his guidence, the parish began the building of a Catholic School for passing on their faith. On February 14, 1949 a fire destroyed the original church. Plans changes and a chapel was added to the school project for the faithful to worship. The fall of 1950 brought the opening of the parochial school and the chapel for worship.
In 1954, on the grounds of St. Lawrence, a grotto dedicated to Mary, the Mother of God, was built. Composed of of rose and clear quartz, mica from the Black Hills, and petrified wood for the North Dakota Badlands it is located on the west side of the property. The steps leading up to the grotto are the original church steps and mark the location of the original church building.
In 1959, under the supervision of Fr. Hugo Backes, the present church was built. It was dedicated in November of 1959. The A-frame buildling can accommodate 150 families and was one of the first handicap-accessible churches of its time.
The Catholic School was closed in 1967 and for several years the building was used by the public school. The building is now the Parish Center; housing the parish offices, classrooms, meeting rooms, and the Flasher Area Food Pantry.
God has blessed St. Lawrence with two faithful vocations. Sr. Jean Loius Schafer, OSF and Fr. Dennis R. Schafer were baptised here and were students at St. Lawrence Catholic School.
The ninety-eight families of St. Lawrence continue to be blessed with strong faith, love for God, and gratitude for all His blessings.
