It's Jesus/Jehovah. Jehovah is the incarnate Christ.
Both Jehovah and Jesus are:
The Alpha and the Omega
The Beginning and the End
The First and the Last
Savior
The Rock
Light
God
Do you think they fight over these titles? Of course not. They are one and the same.
Ah, yeah... thats why Jesus did a complete 180 on the practices mandated by Jehovah in the OT... must have dual personalities...
