The exact definition of who is considered a jew is another matter and has no relevance to this bill. What this oath of loyalty is saying is I recognize Israel is a jewish state and a democratic one and I will be loyal to that state Its not about how do you define a jew. As for UN resolution 181 today doesn't matter because its never been adopted in its original form. Resolution 181 said the jewish state should get 55% of mandate Palestine as a result of war Israel today occupies 78% ( the green line ), there was supposed to be an arab state created but that was rejected, Israel has Jerusalem 181 gave neither jewish or planned arab state even 1 inch of Jerusalem. If we get around to creating an arab state eventually it will be nothing like what the UN envisioned in 1947 when they passed 181 so that resolution has no relevance in 2010. Israel in 2010 has chosen its identity to be that of a jewish state same way some countries define themselves as muslim, chirstian, republican, monarchy. An independent state is allowed to chose its identity the UN doesn't do that and its allowed to make as many demands from anybody seeking citizenship as it wants.
