Well, we can apply a similar argument to say that “Jesus” is unacceptable, since that wasn’t his Hebrew/Aramaic name. I prefer to believe that our merciful God knows what we are trying to say and doesn’t hold something as silly as a mispronunciation against us.
Fine; the article was correct in asserting that the suppression of the use of “Yahweh” was never supposed to be a big deal. No-one is calling anyone a heretic for having used it; simply, the church declines to continue using something which is in error. But it’s not like “Jesus.” Changing Jewish phonemes to Greek ones doesn’t create any incorrect implications (although, it would seem advisable to change Joshua the judge to Jesus, also, so readers would be aware of where Joshua came from.) Changing YHWH to Yahweh, on the other hand, defeats the entire purpose of “YHWH.”
