I recently began my freshman year at a major US university. While in the university's Hillel for a meeting (I.e. not for davening), I saw the Aron Kodesh had engraved on it , fully spelled out, the Tetragrammaton (I don't even want to write the Hebrew letters).
While the Hillel does serve more Reform than traditional Jews, I was SHOCKED that any Jew would so callously write up The Name, without bothering to even change one of the letters. I've been in many shuls and I've never seen the Tetragrammaton written out as decoration, much less so publicly on the aron kodesh.
Am I correct that Halacha forbids such use of The Name? And may I daven in the Hillel with such an ark there?
