While your Master's in Biblical Studies demonstrates strong analytical and research skills, which are valuable, it lacks the necessary foundational knowledge in healthcare management, policy, finance, and operations required for a PhD in Health Administration.
You might be able to apply for a PhD program *if* you supplement your background with significant additional coursework or professional experience in the healthcare field. This might involve taking prerequisite courses, working in a healthcare setting, or obtaining a related certificate. You'd need to contact specific PhD programs in health administration to inquire about their admission requirements and whether your background, coupled with additional qualifications, would meet their criteria.
