Is a theocracy secular

NO. A theocracy is a country that is directly ruled by either (1) a person who claims to be a god or (2) a person who claims to be able to determine the will of the gods. In this case, the religious authority is himself writing the laws of the country and enforcing them. A secular country is one in which religion and the state remain entirely separate from one another and do not interfere in each other's affairs.
