The news is filled with stories about immigration and 'strangers'. Making sense of immigration should be old hat to us by now, given the strength of the argument that we are all immigrants. This is a national story with the unfolding events surrounding the arrival of another ship filled with Tamil Refugees. It is a Toronto story with the issue rising up in municipal elections, a diocesan story with details of Archbishop Collins sponsoring a Iraqi Refugee Family , as reported by the Register's Michael Swan and an international story with Arizona acting as a focal point for arguments from all sides. It is an issue that won't go away, nor should it. It raises fundamental issues of charity and justice and has been on the Vatican's agenda for decades. If we look with either horror, concern or confusion at the situation in Arizona, it is important to realize that the issue is heating up in Canada as well. And as Kelly McParland of the National Post notes, we shouldn't be too smug because the polls aren't painting a pretty picture of our attitudes or values. It's not a simple matter by any means, but it does require thinking through and possibly some hard choices. Without doubt politicians will be getting deeply involved in the issue this fall, which may not be a good thing. As Catholic Bishops from America, Canada and Mexico have recently argued, we need to drill down deep as to causes, consequences and reactions to all parts of the immigration puzzle. And as Catholics, perhaps it's worthwhile to reflect as Ross Douthat did recently on the history of Anti-Catholic immigration scares and the complicated issues raised.Ultimately this is a human story and Andrew Coyne offers an intriguing way to think about the human, economic and even cultural questions.
