The news, as reported by the current Tablet (http://www.thetablet.co.uk/UserFiles/Files/3_Letter_from_Fitzpatrick_to_Archbishop_Cushley.pdf)
of the behaviour of the CDF towards the Edinburgh Newman Circle makes for depressing and confusing reading.
In summary, the CDF responded to an anonymous complaint after a lecture given by Joe Fitzgerald, accusing him of challenging Church teaching on Original Sin. They made no contact with Joe, or with anyone who could give them a proper account of the lecture or of the book that Fitzpatrick has written outlining his views on the subject.
