My test of whether someone is truly Christian is their attitude to LGBT. Any mature Christian will be entirely accepting.
Religion is a tool for helping people to understand and relate to Reality, or alternatively to block out and deny reality in a fruitless search for comfort. Humankind cannot bear very much reality, and those who can bear very little can huddle together in conservative Evangelical churches. There they can be reassured that gays are bad, God made the world less than ten thousand years ago, and everyone outside their little huddle is deluded, and going to Hell. Any threat to that belief system and the bottom drops out of their world, which is why they defend it so aggressively.
And yet, unless they close their eyes, put their fingers in their ears, and shout “La La La” all the time, reality will challenge their falsehoods, and, thank God, so will Christianity. If they actually read the Bible they will realise that God could not create everything, then man and woman on the sixth day, and at the same time create man, then plants and animals, then woman. People do believe impossible or incompatible things, but eventually the scales fall from their eyes. They will also see that while the Bible can be mined for reasons to see other people as bad, it also says that everyone is your neighbour, even those you most despise, then commands you to love your neighbour.
Then the despising falls away. Seen with love, we see the beauty of the Samaritan, and all which seemed most loathsome is seen not to be.
Yet there are these terrible attempts to defend the fundamentalist lie. And some people are just stuck. They cannot turn to Christ, because they prefer the illusion.
I did not like Henry Meynell Rheam, so look at his work more deeply.
