This is a slightly different angle to certification by religious groups, but the broader statement was made about contributing to or supporting religious groups, essentially by product choice in the market generally ...
I wonder how many people buy Sanitarium products?
"All of Sanitarium’s profits are transferred to the Seventh-day Adventist Church in Australia which in turn operates charitable activities which include educational and health services and community programs to improve the health and wellbeing of our communities."
I would be very surprised if there weren't a plethora of other examples - businesses owned by religious organisations and more subtly businesses owned by individuals who contribute heavily to religious organisations.
My point here is that its not necessarily a bad thing if your purchasing decisions contribute to or support a religious group (unless that is a specific personal view). Indeed I wouldn't have the foggiest who I am supporting with most of my product purchases, I don't do an in-depth analysis of their religious status, ethics, green-ness, other investments etc.
For me though, "certification" is a whole different kettle of fish ...
