Rhabboni (G4462) is an Aramaic title of reverent address meaning 'my (great) master' or 'my teacher' — an intensified form of Rabbi. Used by Mary Magdalene at the tomb (Jn 20:16) and by blind Bartimaeus (Mk 10:51), it expresses personal devotion beyond formal recognition.
Mary Magdalene's cry of Rhabboni at the resurrection (Jn 20:16) is one of the most intimate moments in the Gospel. She does not say 'Teacher' — she says my Teacher. The first word spoken to the risen Christ by a human being is not a theological declaration but a term of personal relationship. Jesus' tender instruction — 'Do not cling to me' (Jn 20:17) — redirects her attachment from the physical presence to the coming Spirit. Bartimaeus (Mk 10:51) shouts Rhabboni before he has his sight — faith that names the Teacher before seeing Him. The intensification of the title ('my great master') over plain Rabbi reflects the shift from recognition to devotion.
