Except Zionism is not religious. It is a modern secular nationalist ideology rooted in ethnicity, shared ancestry, history, culture, and language. Indeed, socialism dominated Zionism for a long time.

Many if not most Israelis are not religious, and traditionally, religious Jews (especially the Orthodox; an extreme case is Neturei Karta) oppose Zionism and the State of Israel as a secular ersatz, believing that they must wait for the Messiah to restore Israel.

Of course, in the last few decades, a faction of Zionists have commandeered the messianic for political purposes, but this is not the origin.
