It's just a theological opinion, which may be factual or not. Sometimes, theological opinions are expressed as if they "are facts," but that is why everyone who reads any author should read them in their entirety as much as possible. For instance, I state on my blog that my thoughts are all theological opinions, namely, those of a layperson. If my ideas cause others to think more deeply (or, even more clearly), then my blog will have served its purpose; if not, you can dismiss me and my writings and simply move on to someone else!
