That’s the author’s viewpoint.
He’s a bit dogmatic on his views, but there isn’t any Scripture that has been presented to me to suggest that a Church Rapture will not happen.
There’s at least 2 dozen verses we can refer to and I have multiple times here on this forum.
I perceive that I agree with most of what he says but he leads with an unbiblical position of “those who disagree with him are heretics.” Hard pass.
