In other words, if it didn't say that Joshua commanded the sun and moon to stand still, but merely that they did so, would it be possible to understand it as described from the standpoint of the observer, without implying any comment on the functioning of the superlunary?
Ruben, yes, it
could then be seen as phenomenological, but the weight of assumption would still rest with the historical, which requires it to be interpreted as a literal event. Some literary markers would be necessary to conclude that this was just how it appeared and not rather what actually happened. Even then, however, interpreting cosmological phenomena in Scripture requires an understanding of biblical cosmology. The fact is that the Bible everywhere presents the sun in motion relative to the earth. And it is also a fact that science truly so called allows various geocentric functions, e.g., navigation. Hence there is no reason for interpreting the biblical text in a figurative or less than literal manner. Special revelation requires us to understand that the sun literally stood still and general revelation really offers no voice of criticism to it.
Can you give an instance of a place where phenomenological language might be legitimately seen in Scripture?
I can think of numerous places where the Scriptures speak of things "as it were." E.g., Numb. 9:15, "And on the day that the tabernacle was reared up the cloud covered the tabernacle, namely, the tent of the testimony: and at even there was upon the tabernacle
as it were the appearance of fire, until the morning."
