Paul Harrison, a senior lecturer in consumer behaviour at Deakin University's Deakin Business School, said Christians should not place too much faith in an advertising campaign to convert non-believers or entice lapsed Christians back to church.
He said the subtle messages were likely to confuse and the churches would be better off putting money into understanding why people were turning away from them and what could be done in response.
Well yes, it did occur to me that there might be a significant problem here. I reckon the best potential impact of these campaigns is brand awareness ("Hmm, there are Christians out there, if I ever wanted to find that out") and the worst potential impact is for those who aren't believers to realize how out of touch we are, and for the Christians to feel mildly embarrassed. So the best is not really that good, and the worst is reasonably bad.
Spend the money on feeding the poor I say.
