I think the correction was with the statement that believing in young earth creation was the only way to get to heaven.
It’s not a “salvation essential”,
but the Word is essential to know what is expected of you as a believer,
and that when you start saying this or that part of the Word is “wrong” and that modern secular interpretations are right,
you’re stepping on a slippery slope of self-defining (Gen 3:5) what you want to believe of God’s commands.
“I will hide thy Word in my heart so that I might not sin against Thee”. Well, which part? The “true” part?
