When I have finished writing this, I shall gently drop a book in my recycling bin, although destroying books goes against all my instincts. It isn't that it is a particularly bad book (although, on re-reading it 35 years after its composition, I can say that it hasn't worn terribly well). It isn't that it is a dangerous or corrupting book (although there are one or two points where, knowing what we know now, the reader may wince). It is simply that it has become untrustworthy, something I wouldn't put into the hands of its intended audience - young people asking questions about the Church and their Catholic faith.
