Christianity

So I'm actually a Hindu and I, along with other Hindus, Muslims and Buddhists, am watching the gradual decline of Christianity in the developed West and wondering if the same fate awaits us when our countries become developed.

The way I see it, the last half a century in the West witnessed many social movements like the different waves of feminism, the sexual revolution, the hippie movement, the LGBT rights movement and the socialist movement.

And this led to the gradual acceptance of that which was earlier frowned upon such as contraception, homosexuality, gay marriage, etc. Meanwhile Christianity, especially the Catholic Church, was largely opposed to these things.

But part of me wonders, what if Christianity wasn't so opposed. What if Christian leaders had realised that these things would inevitably gain acceptance in the future and had preemptively started the process of gradual acceptance.

After all religions exist so as long as they're innovative and useful to their followers. And Christianity knows all about this. Despite the fact that the Bible supports slavery, it was the Christian world that led the crusade against it.

Had Christians not rejected slavery, had they stuck to dogma, it's possible Christianity may have started its decline much earlier. But that's not what happened. If anything Christianity went on to spread all around the world.

So I wonder, could the challenge of modernity have been handled differently? And is there still time to make things work? After all Christianity has seen worse days, like being persecuted in the Roman Empire for example.
