First of all, this book, was written. How long ago? By most Christians more or less 2007 years ago....this is pre-1960's woman activists movements blah blah blah...so, we're talking about what exactly? Interpretation. Taking Old English and such into effect, Man can be referred to as a specie of sorts. When one speaks of man, he can refer to either a male of the specie, or the specie in general. For example, Man created fire? Maybe? That's as a group, not some dude sitting there trying to burn stuff. So this could be taken out of context or just outright de-railing it, but I would have to say that "he," God, if there is such a thing, is Genderless. As stated prior, they had to put he. If they made it a she, then the Pagans and such back then, would laugh at the religion, like most laugh at Wicca and other such ridiculous religions.
