What does 'gnostic' imply about a person's knowledge?

The term 'gnostic' is derived from the Greek word 'gnosis', which means knowledge, particularly a type of knowledge that is spiritual or mystical in nature. In a historical and philosophical context, 'gnostic' often refers to certain early Christian sects that emphasized personal spiritual knowledge over orthodox teachings and institutions. Thus, when describing a person as 'gnostic', it implies that they possess a deeper, often esoteric understanding that transcends ordinary knowledge, allowing them to grasp complex spiritual truths.

This understanding aligns well with the correct choice, as it captures the essence of possessing knowledge that is not just practical or superficial, but rather profound and often inaccessible to the general populace. The other options do not reflect this deeper, mystical aspect of knowledge that 'gnostic' connotes.
