It always amazes me that these learned people fail to comprehend that there are foundational principles in any religion that can not be challenged. These principles are call doctrine.
For the Christian faith these principles are for the most part specifically stated in the Bible. They can not be questioned because the Bible says that these things are so.
The Bible says that homosexuality is a great sin and an abomination before God. That can not be questioned regardless of the principle of freedom of conscience, the principle that theologians have a right to think.
Certainly theologians have a right to think. Theologians have the right to question things that are open to question. But some things are not open to question. Some things can not be changed because if those things were to be changed the Church would no longer be the Church.
You can not rip out your houses foundation and have your house remain standing.
I would prefer to state/believe that anyone can question not just theologians. However, not every question is subject to revision from the truth for answer to the question. There has been much revision as to the Bible’s truth.
