What impact did the Aztecs religious beliefs have on Cortes approach to Tenochtitlan?

Because of the Aztec's religious beliefs, when Cortes arrived in Mexico, the Aztecs believed that he was a god. The horses that the men rode and their much lighter skin coincided with a religious belief that they had and so, instead of trying to fight off Cortes and the Spaniards upon their arrival, the Aztecs treated them as gods; lavishing them with gifts and giving them food, gold and other supplies.
