Change the name of the one you worship and you change WHO you worship and the WAY he is worshiped. Substitute a universal title and remove yourself from the True Yahweh. In Exodus 3, Yahweh tells Moses that His Name is Yahweh, then proceeds to explain how He will bring Israel out of the sin of Egypt. They would come to know True Worship, including the Holy Days, after they first learned His personal Name. We establish our beliefs through language.
Words can sway emotion and opinion, as in a good movie or a good book.
Even husbands, wives, and children know what the wrong word or the right word can mean in their relationships. The use of general titles like god and lord promote universalism, which is exactly the opposite of the True faith. One way this is accomplished is by the argument that it does not matter what we call Him. Any name or title is acceptable. As explained, titles like god and lord are general and apply to many different mighty ones, even to Satan himself.
