Saint Scholastica Parish began with a petition by twenty Catholic families in the Aspinwall area asking for the establishment of a parish in the year 1903. In May, 1905, their petition was acted upon with a mission church located on the second floor of McKenzie's Hall at 227 Commercial Avenue. The first eight lots of the present property were purchased from the Aspinwall-Delafield Company for $9,000 and in 1907 the cornerstone of the new church was laid. The building was finished in 1909. The church was dedicated to Saint Scholastica at the corner of Third Street and Maple Avenue. An Aspinwall carpenter, a charter parish member, built the first altar. Within the next decade the adjacent property was acquired and the rectory was built in 1912. Saint Scholastica came into its own as one of the outstanding parishes of the Pittsburgh Diocese.

The original Saint Scholastica building was a small chapel, but it was the intention of the young parish to expand with the growth of Catholic families who joined the church. Membership doubled in the first seven years, and by 1924 construction began on an expanded church and school building which Bishop Boyle dedicated in September 1925. The convent was also built in 1925.

The school, which was staffed by Sisters of St. Francis from Mount Alvernia, opened in September of 1925 as well. There were 159 students and the first eighth grade class was graduated in 1928. The symbols of the Apostles and the Saints were carved on the stone border that capped the building, the center of church life for 43 years and serving as a school for six decades.

Between 1937 and 1944 the church had grown to more than 450 families. The cornerstone for the new church was laid in October, 1949, and the new Saint Scholastica Church, built at a cost of $230,000, was dedicated on June 25, 1950. A large 10ft. crucifix, statues of the Blessed Virgin and Saint Joseph and black slate Stations of the Cross made the new church one of the unique edifices in Western Pennsylvania. Stained glass windows replaced the clear glass windows in 1979.

A new elementary school, dedicated by Bishop John Wright, was built on the south side of Third Avenue in 1959. A new school, parish center and gymnasium building were built in 1985 on the site of the original church and school.

The interior of the church building was renovated in 1995.

Saint Scholastica Parish School became a Regional Catholic School in 1997 through the added support of the Catholic Churches in Blawnox, O'Hara Township and Sharpsburg. At that time, it became known as Christ the Divine Teacher Catholic Academy.

In 2002, a new Pastoral Center was added that provided some much needed space. It includes a parish library, office space for the parish staff, a small kitchen and a multi-purpose room that can be used for both large and small gatherings. By 2005, the Church had grown to over 1,350 families.

The Centennial was celebrated throughout the year leading up to the 100th anniversary of the Parish in 2007. There was an opening mass for the Centennial on April 30, 2006. The celebration included multiple events including several masses, concerts, a large parish picnic and a dinner dance. The streets around the church were decorated with banners and a tapestry was created commemorating the centennial that was displayed in the church. Items were gathered and placed in a time capsule that was placed behind the statue of Saint Joseph during the closing mass celebrated on April 22, 2007.

This brief history of Saint Scholastica Church is in no way complete. It cannot detail the sacrifice and cooperation of parish members, priests, religious sisters, lay teachers, staff, and lay ministers who have made this parish the center for spiritual and community life for thousands of families for nearly one century.
