If you read the article (and the posts), you would have noticed that the bishop is asking those who want to change the teaching of the church to "please leave", not gay people.
A quote from the bishop: “My own view is that if people wish to change the doctrine of our church, they should start a new church or join a church more aligned to their views,” he said. “But do not ruin the Anglican Church by abandoning the plain teaching of scripture.”
He has not told gay people to "please leave". His comment is probably more directed at clergy who are trying to change the doctrine of the Anglican church. This is a clear and reasonable distinction, and hardly unloving or uncaring.
Using that family's tragedy to prove a largely political point about 'alternative families' is insensitive and a non sequitur anyway.
They believe in advancing the church so that people are treated with respect, which a good churchy thing to do and a good thing.
Mark 12:31
The second is this: ‘You shall love your neighbor as yourself.’ There is no other commandment greater than these.”
Romans 13
8 Owe no one anything, except to love each other, for the one who loves another has fulfilled the law. For the commandments, “You shall not commit adultery, You shall not murder, You shall not steal, You shall not covet,” and any other commandment, are summed up in this word: “You shall love your neighbor as yourself.”
Matthew 22
39 And a second is like it: You shall love your neighbor as yourself.
Galatians 5
14 For the whole law is fulfilled in one word: “You shall love your neighbor as yourself.”
Matthew 19
18 He said to him, “Which ones?” And Jesus said, “You shall not murder, You shall not commit adultery, You shall not steal, You shall not bear false witness, Honor your father and mother, and, You shall love your neighbor as yourself.”
Matthew 7
12 “So whatever you wish that others would do to you, do also to them, for this is the Law and the Prophets.
1 Corinthians 13
4 Love is patient and kind; love does not envy or boast; it is not arrogant or rude. It does not insist on its own way; it is not irritable or resentful; it does not rejoice at wrongdoing, but rejoices with the truth. Love bears all things, believes all things, hopes all things, endures all things. Love never ends. As for prophecies, they will pass away; as for tongues, they will cease; as for knowledge, it will pass away.
Luke 10
27 And he answered, “You shall love the Lord your God with all your heart and with all your soul and with all your strength and with all your mind, and your neighbor as yourself.”
Leviticus 19
18 You shall not take vengeance or bear a grudge against the sons of your own people, but you shall love your neighbor as yourself: I am the Lord.
1 John 4
21 And this commandment we have from him: whoever loves God must also love his brother.
James 2
8 If you really fulfill the royal law according to the Scripture, “You shall love your neighbor as yourself,” you are doing well. But if you show partiality, you are committing sin and are convicted by the law as transgressors. For whoever keeps the whole law but fails in one point has become accountable for all of it. For he who said, “Do not commit adultery,” also said, “Do not murder.” If you do not commit adultery but do murder, you have become a transgressor of the law. So speak and so act as those who are to be judged under the law of liberty.
