A woman rubs a candle that has been blessed by a priest over the eyes of a relative during a mass at San Hipolito church in Mexico City February 28, 2013. Bells were rung in different churches as Pope Benedict XVI ended his difficult reign on Thursday pledging unconditional obedience to whoever succeeds him to guide the Roman Catholic Church at one of the most crisis-ridden periods in its 2,000-year history. The congregation believe that the blessed candle will impart protection or healing. REUTERS/Edgard Garrido (MEXICO - Tags: RELIGION SOCIETY)
