As far as the laws of Moses, these were agreed to in advance by the Hebrews. They were not forced on them by God. God has made it clear what his stance is on aliens, Malachi 3: (the last prophet in the OT) makes it clear that the Lord said he will testify against those who oppress and deprive aliens of justice.
I agree that Christians are no longer subject to the law except that which is contained in Acts 15. This new law is written in our hearts by the Holy Spirit and it is founded in love. Jesus gave us the most important commandment and it is to love God with all your heart and all your soul and all your mind. The second he said is like the first and it is to love your neighbor as yourself.
If you can demonstrate how deporting your neighbor demonstrates love for that neighbor then I would love to hear it. In fact, you sound a bit like the Jews who hated the Samaritans.
Interesting. And what if the whole world wanted to come in. We would not be able to sustain that. I work where many form other countries come to study. Many of them would like to stay too, but the I-20 states that they must return to fulfill the contract. It is a struggle for many of them. Obey the rules or ignore the rules. What do you think is most ethical?
Also, what does citizenship mean then? If all can ignore the laws why have citizenship at all? After all, aren't we all citizens of the world?
What about sovernty?
What other laws are we allowed to ignore?
You wrote,"he will testify against those who oppress and deprive aliens of justice." what is meant by justice? Is is right for others to disobey the laws of others? God has placed government over us to maintain order in our society. How does giving those here illegally all of the rights of citizenship following that part.
We are a generous people. Please feel free to sponsor a person or adopt a child from another country. Then the payment for all of their bills falls on you and not society. That's why those exceptions are available.But ignoring our laws and forcing society to pay for the needs of the entire world who would like to immigrate here is not reasonable.
