My interpretation is that JI accepts the scientific findings, like the age of the Earth, but sees it as guidance from God.
I don’t know why he has had some irritation over this. I disagree with it, but I have no problem with faith, so long as they don’t force it on others. I am fine with Christians stating they don’t agree with abortion or gay marriage or whatever, so long as it doesn’t influence the state and how others live their lives. That’s when I would push back.
