He's 63 and in apparent good health. Bishops don't normally retire until 75.
http://ncronline.org/news/faith-parish/scrantons-bishop-martino-stepping-down"Bishop Joseph F. Martino will resign as head of the Diocese of Scranton, as early as next week ...Martino was moving out of the residence for Scranton bishops... The 63-year-old Martino’s six-year-tenure has been distinctive for an almost non-stop round of battles with Catholic academics, Catholic teachers’ union, Catholic politicians and a range of other groups, including his own peers among the Catholic hierarchy.
Martino once famously arrived unannounced at a discussion in a parish of a document on political responsibility that had been passed by the US Conference of Catholic Bishops and declared: “No USCCB document is relevant in this diocese. The USCCB doesn’t speak for me.” He told the assembled crowd that “The only relevant document … is my letter,” referring to a letter on politics he had mandated be read at all masses on a given Sunday.
He has urged priests to deny communion to politicians whose views on the abortion issue differed from those of the bishop. He placed an official notice in the diocesan newspaper informing Eucharistic ministers that they had a duty to refuse communion to anyone whose “unworthiness” to receive was publicly known. The notice emphasized Catholic politicians. He threatened to bar Sen. Bob Casey, a long-time anti-abortion Democrat, from communion for voting to approve former Kathleen Sebelius as federal Health and Human Services secretary. He has battled with officials at Misericordia University, a Catholic college, for hosting author Keith Boykin, a gay rights advocate, and sought to close down the institution’s program on diversity.
Martino sent a letter to the leaders of Irish-American organizations threatening to close the cathedral during St. Patrick’s Day celebrations if the groups “honor pro-abortion officials” by inviting them to speak or otherwise be honored .. he again threatened to shut down the mass if members of the local Catholic teachers’ union were invited to march in the St. Patrick’s Day parade..."
