@TheOtherPaul2 There's a lot to respond to here, so I'll try to take each of your points one at a time:
First, I take for granted that we agree that unity in interpretation of scripture is the ultimate goal (cf. 1 Cor 1:10). When we accept this premise, certain things follow @TheOtherPaul2 In reference to norms/notions, I mean to suggest that we are temporal, fallible beings that do not have perfect objectivity. If we are to interpret in a purely private manner, we are going to fall into error because we cannot fully remove ourselves from our circumstances
