The Diocese of Greensburg will celebrate 75 years of faith this weekend with two days of worship and a distinguished visitor from the Vatican. The events, set for Friday and Saturday in Greensburg, will coincide with the Solemnity of the Assumption of the Blessed Virgin Mary. The weekend’s events will serve as the principal celebration of the diocese’s 75th anniversary, bringing together clergy, religious and parishioners from across its four-county territory. Kulick said the anniversary is an opportunity to recognize the generations of clergy, religious and parishioners who have contributed to Catholic life in the region. For those unable to attend, the Diocese of Greensburg will livestream the Mass on its Facebook and YouTube pages.
