Throughout the Bible there are numerous references on the need to care for the stranger in our midst. The United States Conference of Catholic Bishops point out, both the Old and New Testaments tell compelling stories of refugees forced to flee because of oppression. Exodus tells the story of the Chosen People, Israel, who were victims of bitter slavery in Egypt. They were utterly helpless by themselves, but with God's powerful intervention they were able to escape and take refuge in the desert. For forty years they lived as wanderers with no homeland of their own. Finally, God fulfilled his ancient promise and settled them on the land that they could finally call home.
The Israelites' experience of living as homeless aliens was so painful and frightening that God ordered his people for all time to have special care for the alien: "You shall treat the alien who resides with you no differently than the natives born among you; have the same love for him as for yourself; for you too were once aliens in the land of Egypt" (Lv 19:33-34).
The New Testament begins with Matthew's story of Joseph and Mary's escape to Egypt with their newborn son, Jesus, because the paranoid and jealous King Herod wanted to kill the infant. Our Savior himself lived as a refugee because his own land was not safe.
Jesus reiterates the Old Testament command to love and care for the stranger, a criterion by which we shall be judged: "For I was hungry and you gave me food, I was thirsty and you gave me drink, a stranger and you welcomed me" (Mt 25:35).
The Apostle Paul asserts the absolute equality of all people before God: "There is neither Jew nor Greek . . . for you are all one in Christ Jesus" (Gal 3:28). In Christ, the human race is one before God, equal in dignity and rights.
