Saint Thomas Aquinas on Immigration: Man’s relations with foreigners are twofold, peaceful and hostile

Saint Thomas Aquinas was a Roman Catholic priest who authored the Summa Theologica and Summa Contra Gentiles, which shaped the Catholic Church and its philosophies for centuries. His teachings are still influential. But is the Catholic Church following his teachings on the issue of immigration.

What would Saint Thomas Aquinas say to Pope Francis and the U.S. Council of Catholic Bishops about immigration?

summa Theological book coverIn the column “What Does Saint Thomas Say About Immigration?” John Horvat II asks the same question and provides an answer by quoting Saint Thomas Aquinas. Horvat notes, “Immigration is a modern problem and so some might think that the medieval Saint Thomas would have no opinion about the problem. And yet, he does. One has only to look in his masterpiece, the Summa Theologica, in the second part of the first part, question 105, article 3 (I-II, Q. 105, Art. 3). There one finds his analysis based on biblical insights that can add to the national debate. They are entirely applicable to the present.”

Saint Thomas: “Man’s relations with foreigners are twofold: peaceful, and hostile: and in directing both kinds of relation the Law contained suitable precepts.”

Commentary: In making this affirmation, Saint Thomas affirms that not all immigrants are equal. Every nation has the right to decide which immigrants are beneficial, that is, “peaceful,” to the common good. As a matter of self-defense, the State can reject those criminal elements, traitors, enemies and others who it deems harmful or “hostile” to its citizens.

The second thing he affirms is that the manner of dealing with immigration is determined by law in the cases of both beneficial and “hostile” immigration. The State has the right and duty to apply its law.

Saint Thomas: “For the Jews were offered three opportunities of peaceful relations with foreigners. First, when foreigners passed through their land as travelers. Secondly, when they came to dwell in their land as newcomers. And in both these respects the Law made kind provision in its precepts: for it is written (Exodus 22:21): ’Thou shalt not molest a stranger [advenam]’; and again (Exodus 22:9): ’Thou shalt not molest a stranger [peregrino].’”

Commentary: Here Saint Thomas acknowledges the fact that others will want to come to visit or even stay in the land for some time. Such foreigners deserved to be treated with charity, respect and courtesy, which is due to any human of good will. In these cases, the law can and should protect foreigners from being badly treated or molested.

Saint Thomas: “Thirdly, when any foreigners wished to be admitted entirely to their fellowship and mode of worship. With regard to these a certain order was observed. For they were not at once admitted to citizenship: just as it was law with some nations that no one was deemed a citizen except after two or three generations, as the Philosopher says (Polit. iii, 1).”

Commentary: Saint Thomas recognizes that there will be those who will want to stay and become citizens of the lands they visit. However, he sets as the first condition for acceptance a desire to integrate fully into what would today be considered the culture and life of the nation.

A second condition is that the granting of citizenship would not be immediate. The integration process takes time. People need to adapt themselves to the nation. He quotes the philosopher Aristotle as saying this process was once deemed to take two or three generations. Saint Thomas himself does not give a timeframe for this integration, but he does admit that it can take a long time.
