 Our Mission

The Roman Catholic Diocese of Greensburg calls together the faithful in four southwestern Pennsylvania counties – Armstrong, Fayette, Indiana and Westmoreland​​ – under the leadership of the diocesan bishop, a successor of the Apostles, and in communion with the Holy Father, the bishop of Rome. The Catholics of this diocese, priests, deacons, religious and laity, work together to live out their baptismal call to proclaim, in word and action, the Gospel of Jesus, handed down to us through Scripture, tradition and the magisterium of the church. Our diocesan mission is continually realized by proclaiming God's word; celebrating the sacraments, especially the Eucharist; forming communities of faith; and building a just and compassionate society in this world so that we may be fulfilled human beings on this earth, and so that we may all share God's salvation in his kingdom.

 Southwestern Corner

The Diocese of Greensburg covers 3,334 square miles, and encompasses Armstrong, Fayette, Indiana, and Westmoreland Counties in the southwes​tern corner​ of the state of Pennsylvania. Bordering the western slopes of the Allegheny Mountains, our diocese is part of the region known as the "Gateway to the West." Westmoreland County, home to the city of Greensburg, is primarily urban, while the other three counties are more rural.

The early settlers in our diocesan area came from a rich array of ethnic backgrounds. Beginning in colonial days, people from all parts of Europe migrated to this region. Waves of Catholic immigrants from Ireland, Germany, Austria, Hungary, Poland and Slovakia settled here. 

At the turn of the century, many Italians came to this area as well, followed by the mostly Catholic Irish and Eastern Europeans, representing all of the middle European countries. The diocesan population reflects this rich ethnic heritage. 

In recent years, the region's large blue-collar base has been joined by a growing number of professional and white-collar workers, adding to the diverse human texture of the Diocese of Greensburg.

​The diocese sits atop one of the richest deposits of bituminous coal in the world, some of which has​ yet to be mined. The Allegheny and Monongahela rivers, which traverse the northern and southern sections of the diocese, carry barges that bring coal, river sand and gravel to the Midwest region and south.

Economically, much of the diocese has been strongly affected by the decline of the coal and steel industries. Fayet​t​e County, for example, has experienced many decades of economic depression from the depletion of its coal supply. Indiana County still mines coal that is primarily used as a source of electric power.
 
The northern counties, Armstrong and Indiana, are largely agricultural, and have experienced the decline of small family farms. In Westmoreland County, much of the labor force was employed in the production of steel, and as suppliers to steel companies. The closing of many smaller steel mills has compounded the region's underemployment.
 
The economic realities of the region have also affected the population ​of our parishes. Some towns and cities have lost significant population due to the decline of key industries. The diocese has responded to these demographic shifts by making necessary changes in parish structures, including consolidating or partnering parishes in some areas.
