Vatican City: Pope Benedict XVI on Thursday marked the 50th anniversary of the Second Vatican Council, the church meetings he attended as a young priest that brought the Catholic Church into the modern world but whose true meaning is still hotly debated.
Benedict celebrated Mass in St Peter`s Square, accompanied by patriarchs, cardinals, bishops and a dozen elderly churchmen who participated in the council, and later will greet the faithful, re-enacting the great procession into St Peter`s that launched the council in 1962.
The anniversary comes as the church is fighting what it sees as a wave of secularism erasing the Christian heritage of the West, and competition for souls from rival evangelical churches in Latin America and Africa.
Clerical sex abuse scandals, debates over celibacy for priests, open dissent among some priests and a recent Vatican crackdown on liberal nuns in the US have also contributed to erode the church`s place in the world.
The pope has spent much of his pontificate seeking to correct what he considers the misinterpretation of Vatican II, insisting that it wasn`t a revolutionary break from the past as liberal Catholics paint it but rather a renewal of the best traditions of the ancient church.
In that vein, he decided to mark the anniversary of the council with the launch of a "Year of Faith," precisely to remind Christians of what the council truly taught and seek to "re-evangelize" those Catholics who have fallen away from their faith in the decades since.
It`s necessary, he told his general audience this week, to return to the original documents of Vatican II and "free them from the mass of publications which, rather than making them known, has hidden them."
Benedict was a young priest when Vatican II began, a theological consultant to German Cardinal Joseph Frings, and he has recently reminisced about what the council sought to accomplish, where it succeeded and where it erred.
"It was a splendid day on 11 October, 1962," Benedict wrote in a forward to a commemorative book about the anniversary published this week by the Vatican newspaper. "It was a moment of extraordinary expectation. Great things were about to happen."
Over the following three years, he wrote, the council fathers adopted a series of documents confronting the great questions of the day: liturgical renewal, religious liberty, relations with people of other faiths.
Many of those documents, he wrote, carried an importance that the council couldn`t have known at the time, such as the one revolutionizing the church`s relations with Jews, Muslims and people of other faith.
