It hardly takes a statistician to tell us that a huge proportion of non-government welfare and aid in this country is organised through agencies with a religious heart, such as World Vision, Salvation Army, Mission Australia, Anglicare and Caritas. Then there is the evidence that the religious are more likely to become teachers, nurses and doctors. The recent Religion And Occupation study by the Christian Research Association says about 25 per cent of people in these "nurturing professions" are regular worshippers of one kind or another - much higher than the national average of 17 per cent.
