Most people think that as soon as one speak of Yeshua, then that automaticaly makes that person a Christian. If you can not tell the difference between the influence of the Roman Catholic church Vs. the movement of the patriots, then there is a greater issue at hand.

Paul was ststed in the bible as saying, "That eror has krept into the church". He was speaking of paganism, via the Rome. Rome was that same beast that would later promote Tghe ideology of the Roman Catholic church, which is in direct contrast to the zealots of Hebreism.

As far as Zionism, that term is as open as a 24 hour Walmart. But if we are to narrow the term down, I would associate Zionism with the movement prepertrated by white Jews in the 40's to reside in the land of Israel. The father of Zionism I believe his name was "Theordore Hertzel".
