Do you think the Church helping someone regardless of their immigration status should be criminalized?
BUT the church should not impede the law or lie to protect a lawbreaker. Should an illegal go to a church for shelter and/or aid then the church is well within it's rights to give that aid. After a period of time that individual should make efforts to make himself legal or move on and relieve the burden from that church.
MARK 12:17 Jesus answered them, "Render to Caesar the things that are Caesar's, and to God the things that are God's." They marveled greatly at him.
The law of the land is to be followed as well as the law of the church. It is not the duty of the church to aid a lawbreaker, it is that person's duty to make themself lawful.
