The Yahweh contradiction

[Aion]

I've read that YHSVH was not the Hebrew for Jesus. It was constructed and used in renaissance occult circles and freemasons. Why isn't there earlier evidence of this name if Yahweh used it 3300 years ago?

It was constructed as the Pentagrammaton, yes. There were a few different Hebrew forms for Jesus' name - Yeshua, Yeshu, Yehoshuah. The latter was likely what influenced the creation of the Pentagrammaton through the use of gematria. It does stand for Jesus' name, but it is true that it is historically tied to occult writings in the 1600~.

As for evidence, I do not know, I am not sure I trust that part of the story but there are many things that have been wiped out before. Perhaps it was an expression in some way of Carla's beliefs.
