This is a well-crafted piece of evangelical doublethink. They emphasize respect, empathy, and humility, but show almost none.
Speaking truth is itself a form of love, even if a person doesn’t receive it as such initially. But “in love” also means speaking with great respect, empathy, and appropriate humility. And it means a willingness to love strugglers with deeds (such as hospitality), not just words (1 John 3:18).
Respect, empathy, and humility. This sounds nice, but where is the respect when they don't use her new name or pronoun? They don't even accept that she's Christian:
Jenner professes to be a Christian. Whatever that means, he at least may have potential openness to biblical truth. Let us pray that the truth of the gospel will set him free (John 8:32), knowing how much Jesus loves to redeem and restore sin-broken people.
They're speaking like she's a confused child who needs prayer, not an adult to be debated. They emphasize sharing their "truth" with her and other "broken" transgendered people. This is the opposite of humility and respect. In the last paragraph they finally have a little "humility": (emphasis added)
That is precisely why Jesus came: to deliver people like Bruce Jenner and us from our domains of sinful darkness (Colossians 1:13) and our failing, disordered bodies, and give us glorious, powerful, disorder-free resurrection bodies (1 Corinthians 15:42–44).
But only in the "we're all sinners" sense. They still claim to know the truth (and they still want to stop HER sins now instead of relying on Jesus). If it were only calling for prayer, that would be kinda humble. But instead it tips its hand:
Growing in our understanding of the nature of transgender and sexual-orientation disorders is necessary so that we don’t hold ignorant assumptions and say erroneous and insensitive things to people. And it would be wise for us to anticipate the possibility of discovering someday that our child, grandchild, cousin, nephew, niece, friend, co-worker, or possibly a parent is enduring such a struggle. If that should happen, we want to be safe people for them to talk to.
IE, a main reason for understanding and being nice to transgender people is so they'll come to us for answers. So we can fix them. Because we know the truth. This is evangelism 101: Destroy their self-esteem (while being compassionate), then humbly offer salvation. It works so well!
Here's how it would look with actual respect, empathy, and humility:
"Caitlyn Jenner (formerly Bruce Jenner) is a transgendered Christian. We think that being transgendered is wrong in God's eyes. We hope and pray that God will reveal the truth on the issue to Caitlyn and to us, so we all can avoid doing wrong."
I think most Christians actually feel that way about sin, they just aren't the loud ones...
