I agree with NYer. Even active Catholics often think women priests are an option, that IVF is just fine, and other errors. And when you explain to them, they often still *won’t* “get it.”
In additional to learning, people have to be willing to accept both logical explanation and the authority of the church.
And herein lies the biggest problem. Many Catholics resent being told what to do. In fact, the beauty of church authority is the protection it provides. For example, the Catholic Church never approved artificial birth control. Now, 50 years later, science is beginning to see the impact of hormonal medicines on the body and the environment.
