Vatican City - Pope Benedict XVI baptized 13 babies in the Sistine Chapel during a Sunday Mass celebrated at the altar at the foot of Michelangelo's "Last Judgment" wall fresco.
In a departure from tradition, Benedict did not celebrate the Mass at a small altar set up to face the congregation. Instead, he celebrated it with his back to the congregation, which included the children's parents, godparents, grandparents and siblings.
Decades ago, priests routinely celebrated Mass at altars with their backs to parishioners, but after the modernizing changes of the Second Vatican Council in the 1960s, it became common practice for the celebrant to face the congregation.
The 80-year-old pontiff said it was a special joy for him to baptize the babies, the children of Vatican employees. He asked to families to raise the children with "faith, hope and charity."
As he was leaving the chapel at the end of the ceremony, the pope suddenly looked at his hand, glanced toward the floor and turned to an aide, apparently to say that his papal ring had slipped off. An aide found the ring near the altar and handed it back to the pontiff.
