I heard this was a case. The original intention of the movement was for evangelism towards rabbinic jews, but ended up not being the case.

I think part of it as well is that Evangelicals seem to be adverse to historic Christian tradition because it’s “too Catholic” but want something historical and esoteric to cling to, so they just find their own things. Which is sad, because the reformers often held on to tradition (Especially Martin Luther)
