Pope Francis apologised on Wednesday for slapping a woman who had grabbed him as he greeted a crowd of devotees, shortly before he delivered a speech denouncing "every form of violence against women."The image of a visibly annoyed Francis slapping his way free from the clutches of an admirer as he walked by Catholic faithful on New Year's Eve instantly went viral on social media.A personal apology followed."We lose patience many times," Francis confessed."It happens to me too. I apologise for the bad example given yesterday," the head of the Catholic church said before celebrating Mass at the Vatican.Twitter enthusiasts commented on the pontiff's prompt riposte to the exuberant woman.Francis had greeted children before the Nativity scene on Saint Peter's square and was turning away when a woman who had crossed herself then cried out something, yanked his hand and almost caused him to fall.The 83-year-old pope grimaced and scowled before managing to break free, slapping her hand twice as a security guard intervened.READ: 'God continues to love - even the worst of us' - Pope Francis kicks off Christmas celebrationsThe pontiff continued his tour, walking with some difficulty while maintaining a slightly greater distance from visitors, and gradually relaxed again as he met with other children.Twitter comments revealed some support for his instinctive reaction."I'm not a Catholic, but the woman is wrong. It even seemed as if the Pope experienced pain at one moment," one comment read.Others were less favourable, however."Yikes. She was totally wrong but his reaction was not very Pope like," another commented.In his first Mass of the New Year, the pontiff later declared that "every form of violence against women is a blasphemy against God, who was born of a woman".He noted that the service traditionally celebrates the life of Mary, "the woman who wove the humanity of God".#PopeFrancis acknowledges that we all lose our patience sometimes.
