First, let me note a point on which I agree with him, though.
According to Catholic News Agency,
The archbishop of Guadalajara, Mexico, Cardinal Juan Sandoval Íñiguez expressed his support this week for protests by Hispanics in the United States, saying the “undocumented” are persons who also possess the dignity of the children of God.
That much is true. The protesters are largely baptized people, and the baptized possess the dignity of the children of God. And even the unbaptized possess the dignity of human persons created in God’s image. At the same time, that is a dignity that can be abused, as when people, baptized or otherwise, break the law.
Here’s where the disagreement comes in:
During the inauguration of the Diocesan Museum of the Mexican Martyrs, the cardinal said the undocumented should not be called “illegal” because they are not criminals, but rather people who out of necessity or “ignorance left without their papers.” He said the country to which they travel should treat them with justice and grant them a status that “respects first and foremost their human dignity.”
The U.S. should indeed treat illegal aliens with human dignity, but treating them with justice means acknowledging that they have broken the law, making their presence in this country "illegal."
It may be morally legitimate at times to do illegal things out of moral necessity, but this does not automatically make the act legal under civil law (though in some cases civil law may honor a necessity defense).
The Cardinal Archbishop is not dealing straight here. The number of illegal immigrants from Mexico who out of "ignorance left without their papers" is diminimously small. Children may have been dragged along by their parents in that condition, but the number of adults who did so is extremely low or non-existent. They knew darn well that they needed the appropriate papers to cross into the United States. Otherwise they wouldn’t be using obscure desert trails and paying coyotes sums of money to smuggle them across crammed into the backs of vans and semi-trucks.
I’m sorry, but sometimes the truth hurts, and the truth is that non-citizens who have come into this country illegally are illegal aliens by definition.
We do neither them nor the American people a favor if we try to paper over this reality with terminology that would seek to mask this fact.
To do so only distracts from the core moral questions of whether their presence in this country can be morally justified or not (that’s where the necessity defense plays a role) and what is to be done about the situation.
