Final answer:
A respected theologian can be synonymously called a student of divinity.
Step-by-step explanation:
A synonym for a respected theologian would be D. student of divinity. A theologian is someone who studies and writes about religious beliefs and practices, and a student of divinity is someone who is studying to become a religious leader or scholar. This term specifically refers to someone who is studying divinity, or religious studies, at a higher education level. Other options listed, such as pantheist, theocrat, and believer in a deity, do not specifically convey the same meaning as a respected theologian.
