Pope decries abortion, same-sex marriage at Fatima

Benedict made the comments to Catholic social workers, health providers and others after celebrating Mass before an estimated 400,000 people in Fatima. The central Portuguese farming town is one of the most important shrines in Christianity, where three shepherd children reported having visions of the Virgin Mary in 1917.

Benedict's visit to Fatima on the anniversary of the apparitions was the spiritual centerpiece of his four-day visit to Portugal, which ends Friday. It was cast by Vatican officials as evidence that he had turned a page in weathering the abuse scandal, which has dogged him for months.

The Vatican spokesman, the Rev. Federico Lombardi, pointed to the turnout in Fatima and said it was "very beautiful and encouraging" that pilgrims hadn't been deterred in expressing their faith despite months of revelations in Europe about priests who molested children and bishops and Vatican officials who turned a blind eye.

The faithful understand "the capacity of the church to effectively overcome—via conversion, penance and prayer—the dimension of real sin there is in our community," Lombardi said.
