Some Christians today are still arguing if women can be in leadership. That seems laughable to me, though I realize that sounds uncharitable. More Christians today are arguing or struggling over the subject of same-sex marriage/attraction or whatever. When I think of some of the ethical questions that will face Christianity in the future, I wonder if some of our questions today will seem silly or small?
For instance, when it comes to joining crocodile DNA to human DNA so that our hemoglobin can go on less oxygen, so that we can walk around Mars with a less oxygenated atmosphere… yet those and other DNA changes start separating humanity into separate species who cannot interbreed… is that ok or not from the perspective of the Christian faith?
When we get the carbon nanofibers to the point we can build a space elevator (google it) and make the other planets more accessible because we don’t need to get out of Earth’s gravity well for takeoff, will it be ethical from the Christian faith’s viewpoint to spend the world’s wealth on an elevator when children across the Global South still don’t have clean water?
When trillions start getting dumped into terraforming Mars into a liveable planet like Earth (it’s about as close as it can get already), will we consider it ethical to do so when those same children in the South still don’t have clean water? What does the Second Coming look like from Mars? Will Christians argue that God made only Earth for humans?
Will creating meteor-buster missiles (to protect Earth from a mass extinction from a large hit) be considered by Christianity prudent, or lacking faith in God?
These are only up close, short term questions almost upon us. What about questions of dumping all your memories onto a computer chip and then reviving you in a cloned human’s brain? Is that people taking resurrection into their own hands?
What about taking a human brain and placing it in a mechanical body so that settlers don’t need life-support systems, and can settle on the moons of the outer planets like Uranus or Neptune? They will never be able to biologically reproduce, and their only flesh-and-blood part would be their brain — everything else prosthetic. Is that ok by Christian theology?
Point being, we have some wild and tricky questions coming. Sometimes today’s seem tame.
