>>Are you saying that the good theologies in Judaism came from men of a false religion and not from God?<<
It's not all "good theology." Jesus specifically spoke against Zoroastrian dualism when he said, "a house divided against itself cannot stand." Unfortunately, a false Zoroastrian concept of Satan persists within Christianity. (Hitler even deliberately confused the two, calling Christianity a Jewish corruption of Zoroastrianism.)
Some concepts which *did* first exist in Zoroastrianism may have been sanctified, purified and prophetically induced into Judaism, however. The Zoroastrian concepts of the afterlife, while corrected by Jesus, were closer to Christianity than had existed previously. (There is also a heavily Greek influence in Christian concepts of the afterlife.)
There is a false notion that some Christians have that says that ALL beliefs of ALL non-Christians are Satanic. The truth is that God has made the Truth visible in the Natural Law, making it accessible to all people, except for the fact that our reason is clouded by sinfulness. Monotheism was known by the Egyptians long before the Israelite enslavement; the Greeks innovated knowledge of the soul and of Hades; the Babylonians recorded an approximation of the Creation account a millennium before Abraham.
But where Calvinism concludes that that cloud absolutely prevents any insight and thus must deny the historical origins of proto-Judaic doctrines, Catholicism believes in prevening grace, wherein such discernment can prepare people to know the ultimate truth.
At the same time, such primitive spirituality is a mix of half-turths and lies. The prophets distilled, sanctified and purified such half-truths, guided by the Holy Spirit to fulfill and turned their lies into truths.
