Then you better have a good look at tanakh which clearly indicate that YHWH is translated to I AM in certain places and LORD on others.<quoted text>
Isaiah never believed in a triune God. I AM is also not a name like YHWH or YHVH. I agree you do not worship the Almighty LORD. It is true that you worship a God that does not exist.
Isaiah 6:8 refers God as we, so definitely a Triune God.
