re: Would you refuse to speak to your adult kids if they changed their religious beliefs?

Matthew 5:43-48 But I tell you, love your enemies and pray for those who persecute you, 45 that you may be children of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous.

Basically love all people regardless what they think or believe.
