Archēgos

Greek archēgos — the founder-leader who goes first and brings others through; translated variously “author,” “captain,” “prince,” or “pioneer.” Hebrews calls Jesus the archēgos of salvation (Hebrews 2:10) and “the pioneer and perfecter of faith” (Hebrews 12:2) — the originator who opens the path and runs it to the end, the companion word to prodromos. Synonyms: pioneer, author, captain, prince, founder, trailblazer.
