Discourses of Brigham Young, pg. 204; “If a child or relative of mine forsakes the Gospel, the holy Priesthood, his God, and the Kingdom of God, farewell to that child or relative, whether near or distant. I own none as relatives, only those who love and serve our Lord and Savior, Jesus Christ. All that belong to my Father’s house I own. I love them, I delight in their society, no matter whether they are poor or rich, learned or unlearned, if they observe the laws of the Kingdom of God and live according to it. 9:155.”

1 John 4:20; “If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, how can he love God whom he hath not seen?”

If a child of yours attended a different church would you shun them?  Where in the Bible does it say to do so?
