I'm a Christian and his statements represent a gross misunderstanding of Christianity.
"I don't see Christ's redemption limited to human beings," Reverend Dr. Christopher J. Benek
The Bible time and time again states that Christ died for our disobedience towards God. The penalty for this disobedience is death. The only way to reconcile our disobedience to a Holy God was for someone perfect to die on our behalf. This is person is Christ. A person who follows Christ is a Christian. What reconciling does a tree/rabbit/AI need to do? (Answer: None). In Genesis, humans were given dominion over the Earth. We are responsible for what we have been given. So any AI we create, by proxy, is our responsibility.
Also, In Christianity, we are in fact, a soul. Our bodies are merely vessels. All is meaningless, there is no purpose if we cease to exist after we die. Christianity is 100% pointless if we do not have a soul. So to "convert" AI is just as useful as converting trees/rabbits/etc...
This line of thinking from Christopher bothers me - similar to how climate change deniers bother scientists.
