Nelka’s answer doesn’t leave us much, I;m afraid. But can we say that absolute Knowledge is God. Indeed in another religion Mind is a synonym for God. Therefore what we as humans call knowledge is vastly relative, even is some of it is consistent with repeated observation. What continually baffles me is that knowing the limits of human mentality and practicing what is admittedly a faith, adherents of the nearly 40K Christian sects and nearly every other religion claims to have not only “knowledge,” but “knowledge” sanctioned by Deity. Of course they are all right.

For instance, one can have knowledge of the Bible and its words according to the version they study. They might “know” the Bible, though even some such have provided bothe comedy and embarrassment in demonstrations of such. And there is continuous and vitriolic argument even among scholars and the religious as to meaning and intent. If you have studied anything significant about translation, meaning, collections, canons, nuance of tongue, etc, you know there is much to be contentious about. The George Lamsa translation provides some fascinating insights into this matter, he being a native speaker of Aramaic.
But that is all yet relative knowledge and internally referential. An “outside” study of the Bible might bring different ideas to light by treating it as a phenomenon as distinct from pre-accepted Divine revelation. So it fascinates me that people for the most part uncritically accept the tenets of their birth religion, even if it
is the right one. And all the people in the “right” religion each, when it comes down to it, do not really have an encyclopedic understanding of what officially constitutes their faith. There are some incidents relative to practitioners of heavily Bible based religions that do not serve them well as far as knowing what actually is in the Bible and what it might actually imply. This is particularly true if one looks at the Bible through the eyes of some middle Eastern and Eastern philosophies that would render a radically different take on, for instance, the utterances of Jesus. According to some of those, and they are consistent, the original message of Jesus might have been something rather different than what it is taken to be by the vast majority of Christians today.
But as far as using “knowledge” as a weapon, one has to ask which knowledge about what and relative to what question. And does the speaker or listener confuse knowledge and faith, or take them to be the same, especially as pertaining to their own faith? A common refuge in arguments, usually unfounded, is “I
know x is so.” Maybe, maybe not, and maybe both and in part depending on relativity. Or maybe it is true at one level and context but not another. But in any case, to use actual or purported knowledge as a weapon as distinct from an educational tool reveals low maturity on the part of the wielder, and perhaps even lack of knowledge, especially self knowledge.
