Vatican spin

The Vatican has asked for prayers worldwide for those who have been sexually abused by priests. A laudable idea. Then at the end of the statement the cardinal adds that just one per cent of priests have abused. Is this a scientific fact to which he is privy? It is spinning at its best. From evidence the figure appears to be much higher. Why pick the tiny number 'one'?
The church seems to have learned little or nothing from what has come to public knowledge over the last ten to twenty years.
The culture of silence trundles on, heads in the sand when it suits. Indeed there is a developing tendency which is most worrying.
Maybe Donald Cozzens in his lecture in Killarney this evening will throw some light on the topic. Light is needed.
