Compare Israel's proposed oath to the one required of new citizens here in the U.S.: "I hereby declare, on oath, that I absolutely and entirely renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty of whom or which I have heretofore been a subject or citizen; that I will support and defend the Constitution and laws of the United States of America against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I will bear arms on behalf of the United States when required by the law; that I will perform noncombatant service in the Armed Forces of the United States when required by the law; that I will perform work of national importance under civilian direction when required by the law; and that I take this obligation freely without any mental reservation or purpose of evasion; so help me God." The military service and "so help me God" parts are optional if you are a pacifist or an atheist. http://en.wikipedia.org/wiki/Oath_of_Allegiance_(United_States). Obviously, there is nothing about Christianity in the oath, or in the Constitution. Only an apartheid state needs an oath like this.
