These are some of the thoughts of Saint Thomas Aquinas on the matter of immigration based on biblical principles. It is clear that immigration must have two things in mind: the first is the nation’s unity; and the second is the common good.
Immigration should have as its goal integration, not disintegration or segregation. The immigrant should not only desire to assume the benefits but the responsibilities of joining into the full fellowship of the nation. By becoming a citizen, a person becomes part of a broad family over the long term and not a shareholder in a joint stock company seeking only short-term self-interest.
Secondly, Saint Thomas teaches that immigration must have in mind the common good; it cannot destroy or overwhelm a nation.
This explains why so many Americans experience uneasiness caused by massive and disproportional immigration. Such policy artificially introduces a situation that destroys common points of unity and overwhelms the ability of a society to absorb new elements organically into a unified culture. The common good is no longer considered.Right! And many of our bishops are primary culprits in enabling the destruction of our country and the common good. It's unfortunate that so many nations have corrupt governments that exploit their people. (Like ours doesn't?) But the answer is not to destroy what little unity we have in the U.S. by flooding the country with illegals, many of whom have no interest in assimilating but simply want to cash in on government handouts bankrupting communities and stealing from the taxpayers. (Attention, bishops, stealing is a sin!) Pray for our bishops! Many of them are blind guides drawing their flocks to error and sin. Never forget that prudent Catholics test the spirits.
