If you agree Jesus wouldn’t have followed a superstition to avoid the divine name then I don’t know what exactly we disagree about - I'm not sure we have anything to disagree about in this thread.
I'm just pointing out how the divine name was used so repeatedly in the OT that it almost became monotonous, whereas it was only used sparingly in the NT.
I think the words you’re looking for are ‘hallowed be thy name’ - yes, those words were part of the model prayer. But Jesus encouraged his followers to call God 'our Father'. Which sons or daughters call their father by his own name? I certainly don't call my father by his own name ...
