This query touches on several important aspects of Catholic teaching regarding justice, charity, immigration, and the role of law. Here's a breakdown:

1. Catholic Social Teaching on Migrants and Refugees:

• The Church recognizes the right to migrate to sustain one's life and family 1.
• It also acknowledges the right of nations to control their borders, but this right is not unlimited and must be balanced with the duty to welcome newcomers with charity and respect for human dignity 12.
• The Church emphasizes the importance of welcoming, protecting, promoting, and integrating migrants 3.
• Migrants should be welcomed with humanity, recognizing that every human being is a member of humanity and possesses the same dignity 3.
• The Church is particularly mindful of family separation and the importance of reuniting separated family members 1.

2. Justice and Charity:

• Justice is a moral virtue that involves giving God and neighbor their due 45.
• It is a constant and firm will to recognize the other as a person 6.
• Charity, on the other hand, is a theological virtue through which we love God above all things and our neighbor as ourselves for the love of God 789101112.
• Christian charity embraces even what is not lovable and offers forgiveness 11.
• Love "surpasses" justice, but at the same time, it finds its verification in justice 13.
• You cannot "give" what is yours to another without first giving him what pertains to him in justice 14.
• Justice should be tempered with mercy 14.

3. Role of Law and Civil Authority:

• The Catechism states that immigrants are obliged to respect the material and spiritual heritage of the country that receives them, to obey its laws, and to assist in carrying civic burdens 115.
• Political authorities may make the exercise of the right to immigrate subject to various juridical conditions, especially regarding the immigrants’ duties toward their country of adoption 15.
• Public authorities have the responsibility of controlling waves of migration with a view to the requirements of the common good 16.
• The Church affirms the rule of law and encourages the use of lawful immigration pathways 1.
• However, the right to control borders is not unlimited and must be balanced with the duty to welcome newcomers with charity and respect for the human person 1.
• Detention of immigrants should be an exception, not the rule, and governed by well-defined criteria 17.

4. Specific Scenario Considerations:

• Actions of Judge/Charity Director: The actions of the judge and former Catholic Charities director must be evaluated considering both justice and charity. Did their actions violate the law? Did they act with the intention of charity and upholding the dignity of the undocumented immigrant?
• Obligations of Immigrants: Undocumented immigrants are still obliged to respect the laws of the country they reside in 15.
• Primacy of Human Rights: The primacy of human rights and human dignity should be emphasized over national interests 17.
• "Welcoming the Stranger": The Gospel mandate to "welcome the stranger" requires Catholics to care for and stand with newcomers 2.

In addressing the scenario, it's important to consider the complexities of balancing legal obligations with moral imperatives, with a focus on the principles of human dignity, justice, and charity within the framework of Catholic Social Teaching.
