It's like that openly-atheist United Church of Canada pastor who's getting breathless write-ups in hyper-liberal 'Christian' media lately. (Have you seen any of this stuff?)
I'm sure Gretta Vosper has provided counsel to countless many over the past 19 years. I'm sure they are thankful for her advice. I know you struggle to understand how an atheist can do that (often, dare you imagine it 'better' and for more humanist, dignified reasons than those who are devout) and why indeed so many atheists are attracted to 'professional ministry' or continue in it after their faith leaves them. Maybe you should actually go and 'see this stuff.'
