Answer:
Christianity first appears in Palestine, among the Hebrews, and it's originated in the Jewish religion. The influence of this religion in the Roman Empire, as monotheism as general, effected considerably after the conversion of several emperors to this religion in the first century AD, Christianity became the official religion of the Empire.
Explanation:
Initially, it was only a religious movement in the Jewish culture, but it spread for the regions of Asia Minor and Mediterraneo. The milestone which separates Christianity to the Jewish religion is the birth of Jesus Christ. This religion began to be part of the Roman Empire when Palestine was attached to the Empire in the first century AD but only became stronger after Constantine officially consider this religion the Empire's main belief. In 325 AD, Constantine began a policy to approach the State and Christianity. Indeed, while Christianity favored the resistance of the popular strata, it was easily acceptable to the more powerful strata on the other because of the rigid organization of its Church.

<span>1. California does not deserve a seat in the United Nations. </span>
<span>2. The UN is only for nations; people in California are US citizens; they do not have a culture nor a culture that is exclusive to the rest of the US. In this sense, California is not a nation. (this is the definition of a nation bit.) </span>
<span>3. Federalism, the system where states and national governments share power. California (states in general) does not have the power to enter into treaties with foreign countries, nor regulate commerce with foreign countries. These powers are exclusive to the national government. This would mean that it cannot be given a seat, where these powers would be put into California's hands. I guess states governments would also fit into here somewhere. </span>
