Loving God and my neighbor as myself.
All of those approximations are not the divine name. They are insults of the divine name.It was not a commandment to say something other than the Divine Name. Lord is not Yahweh, or Yahveh, or Yehovah, or however someone might pronounce it. Used properly, with reverence, it certainly is not wrong to say God's personal name. It is in the scriptures thousands of times.
The reason we say Lord, God, etc., is because we don't want to take the chance of using the divine name in vain, we don't even want to approach that lest we go over the line on accident. Proper use would be in prayer or worship (but not casual talk). However, we don't have that option these days, since the pronunciation of the Name is lost.
