Possibly his concern is over the salvation of people who think the earth is a sphere. RR has posted a couple of recent threads about heresies, questioning whether people who believe any heresy can be saved. Perhaps he thinks that believing the earth is a sphere is heresy, and anyone who subscribes to it is not saved.
Maybe he's trying to save us.
That may be the case, and I've allready gathered that from past posts.
I know he believes if a person dies in heresy there dammed.
I really believe God is intelligent enough and has the means to know if such person may have believed in innocence.
I would of thought 99 percent of Christians here not believing as he does,
or prepared to change there minds, should be enough to have give it up allready.
For that reason I say this is bordering on OCD.
He should let it go as God is not going to dam a person for something they believe on good faith such as the earth being round. 😊
