Zionism is flexible, it started out secular but it changed over time to better cater to the audience (religious Zionism).

These aren't inherently contradicting because the central theme of zionism is and will always be ethnonationalism + fascism. As long as those aspects remain, zionism can be whatever it needs to be to cater to its audience.

Judaism as a religion believes that they will be led to the promised land by the return of their messiah. Zionists decided to cut that part out, defy their scripture and do the return part by themselves. Zionism sees Jews as purely a race.

Zionism at its very essence is completely Atheistic. Its father Theodor Herzl was an Atheist.

Zionism as a national movement that rebelled against historical Judaism was mainly atheistic. Most of its leaders and activists ceased believing in redemption through the coming of the Messiah, the long-standing essence of Jewish belief, and took their fate into their own hands. The power of the human subject replaced the power of the omnipotent God.

The rabbis knew that, and were terrified – and, therefore, almost all of them became avowed anti-Zionists. From Hasidic rebbes Sholom Dovber Schneersohn, the Admor of Lubavitch (Chabad) and Yehudah Aryeh Leib Alter (the Admor of Gur) to leading U.S. Reform Rabbi Isaac Mayer Wise, founder of the Reform Central Conference, mitnagdim and Hasidim, Orthodox, Reform and Conservative, all saw the rise of Zionism as the end of Judaism. Due to the sweeping opposition of the rabbis of Germany, Theodor Herzl was forced to transfer the First Zionist Congress from Munich to the Swiss city of Basel.
