Thank you for the courtesy of correcting my careless typo.
I generally allow people to self identify. Many people who believe in Christ as Savior also do not require the Bible to be read literally in sections like Genesis. Some here would challenge their professed Christianity.
Personally, I think that’s sufficient, believing and accepting Christ as savior, but as they grow, they come to understand Jesus meant what He said 100% of the time, about every subject.
I’ve met cafeteria Catholics, Protestants all across the spectrum, some worse than others, but it’s not my place to judge them. But I would say it’s a Christian duty to warn them.
One doesn’t get to pick and choose, it doesn’t work that way.
