Abstru'seness. n.s. [from abstruse.] The quality of being abstruse; difficulty, obscurity.
It is not oftentimes so much what the scripture says, as what some men persuade others it says, that makes it seem obscure, and that as to some other passages that are so indeed, since it is the abstruseness of what is taught in them, that makes them almost inevitably so; it is little less saucy, upon such a score, to find fault with the style of the scripture, than to do so with the author for making us but men. Boyle on the Scripture.
