Why did Jefferson assert that religious freedom is a natural right that cannot be infringed upon?

Thomas Jefferson asserted that religious freedom is a natural right because he believed it is an inherent aspect of human dignity and autonomy. He argued that each individual has the capacity to choose their beliefs, and that government interference in matters of faith violates the fundamental principles of personal liberty. Jefferson viewed the separation of church and state as essential to ensure that individuals could practice their religion freely without coercion or persecution, thereby fostering a more just and equitable society.
