The odd thing about the Exclusive Brethren pronouncement, surely, is its basic theology. When it refers to the "serious decline in moral standards resulting in bad laws, strikes and union strife, poor economic management, high unemployment, very high interest rates and difficult trading conditions” it seems to be saying that moral standards are important primarily because of their economic impact. God evidently disapproves of adultery, for example, not because it leads you down the primrose path to hell but because he thinks it has deleterious effects on your economic management. There's a whole entirely new new testament in this, one where you read about Good Samaritan Hostels Inc., the woman taken in unionism, and Jesus driving the moneylenders into the temple.
You learn something new every day.
