Neil O,
Bishop Williamson did not advise a woman to attend the N.O., but only explained to everyone publicly that he did not advise AGAINST her doing so, for personal reasons applicable only to her case and to others like her. He was very clear in saying that he does not recommend the N.O. for everyone, and that it constitutes an objective danger to the faith of Catholics in general.
I must protest. "and that it constitutes an objective danger to the faith of Catholics "
Full Stop! The Church forbids a Catholic from knowingly placing themselves where a danger to the Faith exists.
We can go no further at that point, and I do not see any possible circuмstance where that does not apply, and therefore any counsel which controverts this is wrong and should not have been given.
She came for permission and absolution from something that she suspected or knew was wrong and she received both and others who are of the same mind did as well.
Very Bad.
