Jesus is the Father manifested in the flesh (1 Timothy 3:16). He is the image of the invisible God (Colossians 2:9). If you mean, is the Father greater than the flesh, then the answer is certainly yes. If you mean, is the invisible God greater than the image He took on for the salvation of man, then again the answer is yes. If you mean, is the first person of the trinity greater than the second person of the trinity, then we have no answer for that because the trinity is not a biblical doctrine.
