The coat of arms of the Diocese of Harrisburg is based on the arms of the Penn family and the Harris family, for whom the city of Harrisburg is named. The shield, divided by a Latin cross (a symbol of the Catholic Faith), bears a shamrock to honor Saint Patrick, the patron Saint of the Diocese and of the Cathedral Church.
The black chief (upper partition) displays two silver roundels derived from the arms of William Penn, the founder of Pennsylvania. William Penn bore as arms a silver shield, thereon a black fess (horizontal band) charged with three silver roundels. The crescent from the arms of one of the branches of the Harris family represents John Harris, who migrated to America from Yorkshire, England, and in 1712 settled Harris’ Ferry, now known as Harrisburg. The crescent is also the revered lunar symbol of Our Lady of the Immaculate Conception, a title for Our Lady entrusted to the Church in America, naming her Protectress of our nation.
Catholicism in what is now the Diocese of Harrisburg traces its beginning to the 1720s when Jesuit missionaries established the “Conewago Mission” (today the site of the Basilica of the Sacred Heart of Jesus) in what is today Adams County. From there Catholic settlements developed as the faith spread east, west, and north throughout south central Pennsylvania.
Consistent with its policy of providing financial disclosure, the Roman Catholic Diocese of Harrisburg has worked hard for many years to provide financial transparency. On February 19, 2020 the Roman Catholic Diocese of Harrisburg filed for Chapter 11 bankruptcy.
On March 3, 1868, Pope Pius IX, accepting the recommendation of the Bishops of the Second Plenary Council of the United States of America, issued a decree establishing the Diocese of Harrisburg. We give thanks to Almighty God for the founding of our Diocese. The 150th anniversary of our Diocese was celebrated from March 3, 2018 to March 3, 2019.
