Well, I'll weigh in once, then let you guys continue your discussion, but Pius XII did NOT want Israel to be settled back into their Biblical Homeland after WWII ended.
Here is a LINK to the historical document, written by Pius XII's OFFICIAL REPRESENTATIVE to President Roosevelt, urging Roosevelt to oppose the creation of Israel, or failing that, to re-settle the Jews into some OTHER piece of land OTHER than the one God GAVE ISRAEL FOREVER.
My position is that I cannot see how someone, who considers themselves a Christian, would oppose the clearly written Will of God that Israel was to posess the land He promised to Abraham FOREVER.
If Roosevelt had acceeded to Pius's will and re-settled Israel into some random piece of land in, say, Morroco or Tunisia, it would have provided Bible critics with all the ammo they needed to discredit God's Holy Word, and would have provided a rationale to disregard the Holy Bible.
I am prepared to support Israel on the simple grounds that they have as much right as the Arabs to have their own country, but God twice took away the Promised Land. As to the establishment of a Jewish state, the potential for violence was already clear by the 1930s, because the Arabs were already wild. If Rommel had gotten to Cairo, the whole of Araby would have united behind Hitler in the blink of an eye.
From the casual observer's eye, it seems that the creation of a Jewish state has been an horrible catastrophe for the Jewish people. If the purpose of it's creation was to create a safe place for Jews, then it is an epic failure.Jews are more safe anywhere else in the world. It looks like Pius XII was a savior for the Jews even after the Nazi's were vanquished if he opposed it.
If you think that the creation of Israel is to fulfill bible prophecy then you are indeed a scholar!
