Pope Francis has backed parents who smack their children, providing the child's "dignity" is maintained.
He made the remarks during his weekly general audience at the Vatican, which was devoted to the role of fathers in the family.
The Pope outlined the traits of a good father, as someone who forgives but is able to "correct with firmness" while not discouraging the child.
Some child welfare campaigners have questioned his comments.
The Pope said: "One time, I heard a father in a meeting with married couples say 'I sometimes have to smack my children a bit, but never in the face so as to not humiliate them.'
"How beautiful," he added. "He knows the sense of dignity. He has to punish them but does it justly and moves on."
Bravo! I'm delighted that the Holy Father has seen fit to defend the Biblical disciplining of children.
This is really going to annoy the secular-liberal establishment.
