Around the turn of the century Australians became aware of a growing religious minority within their society which was not readily assimilating and did not share the same mainstream values. Although professing loyalty to Australia, many questioned this as their ultimate loyalty was to clerics overseas. This group also claimed to worship the same God but most people agreed that the religion was incompatible with Biblical Christianity. Their isolation was enhanced by their tendency to build their own schools, where women in repressive neck-to-toe robes and head-coverings taught the religions traditions of their country of origin. Many of this religion were involved in violent struggles overseas against our allies, and some were involved in terrorist acts. This group also tended to have more children than mainstream Australian families, increasing the anxiety among Australians that their values would be overtaken.
Of course I am talking about the turn of the 20th century and the Irish Roman-Catholic minority. With the benefit of hind-sight, most of those fears turned out to be unjustified and the Catholics have assimilated into society. What was once a very firm distinction between Protestant and Catholic has increasingly turned into co-operation, as in the recent World Youth-Day events.
What then of the enemy within? Could it be that our real struggle is within ourselves, and we externalise it at our peril?
