 As of 2009 , the congregation had approximately five thousand two hundred and nine parishioners . Mount Saint Peter Church serves as a symbol of faith and what can be accomplished when people work together for a common belief , hope , and dream . The church 's new motto , adopted in 2004 , reflected this balance : " to restore all things in Christ ... with the fire of love . " This motto serves as a constant reminder of the history of the parish . The beauty of the Mellon Mansion was restored by the congregation and turned into a House of God . This was done through a strong love of Christ , faith , and neighbor . The names of the volunteers who helped build the church are carved in the marble inside the main entrance of the church and serve as a token of the congregation 's appreciation . Many of today 's parishioners are descendants of those volunteers and are proud to tell the story of their forefathers who gave them this church in which to practice their faith .
