Matthew 25 and the Immigrants

In a community in California, a bishop has asked his diocese to assist the immigrants with temporary housing, food and clothing.  This has created an uproar and Rush Limbaugh has interviewed parishioners from this parish who are opposed to this plan.
    If this was a ghetto in Jerusalem in 30 AD, and a group of Samaritans (women and children) migrated into Jerusalem because of a plague in Samaria, what would Jesus and his disciples do?  Would he tell the disciples to contact the Roman authorities to take care of this problem? I suspect Jesus would kneel at their feet and bind their wounds and give them cool water to drink and bread to eat, despite the risk of contracting infectious diseases that they brought with them. He would tell his disciples that whatsoever you do for them, you have done it unto me, even if they had "lice crawling down their faces."  Putting politics aside, I would expect nothing less from the Catholic Church to offer this assistance. They are following Matthew 25.
