Gadol, exactly. Except Jews are more advanced. We don’t really have traditionalists like Thomas. As we discussed here many times, most Jewish groups are doing things differently now than centuries ago – nobody wore black during Gemora times except in the act of committing a sin (Moed Katan); 400 kids studied in an only Volozhin yeshiva 200 years ago, etc. But, similarly to Thomas, the latter “innovations” sound less like innovations.
On a more theoretical level, there is a difference between “originalism” in interpreting Torah and interpreting a humanly produced contract.
