Luke loves to refer to Jesus as the Lord.
Elizabeth calls Mary “the mother of my Lord,” when baby Jesus is in utero. Those petitioning Jesus for help will defer to him as “Lord.” It is “the Lord” who appoints seventy-two and sends them out on their mission.
And it is “the Lord” who turns to look at Peter after Peter has denied him for the third time (22:61).
And then… nothing.
Throughout the trial before the elders, Jesus is not referred to as “the Lord.”
Throughout the trial before Pilate, Jesus is not referred to as “Lord.”
Standing before Herod, he is simply “Jesus.”
Before the crowd, he is simply “this man.”
Led to the cross, he is Jesus. Crucified, he is mocked as the would-be Christ or would-be King of the Jews. But he is not called the Lord.
Through the taunting of the one bandit and the petition of remembrance from the other, he is derided as “the Christ” or simply called Jesus.
It is “Jesus,” not “the Lord” who gives up his spirit, and “Jesus” whom the women watch from afar.
“Jesus'” body is buried.
But on the first day of the week, when the women come to anoint the body with their aromatic spices they discover less than they came to find. And also find out that they should have been looking for more.
They find that the body of “the Lord Jesus” is missing.
The risen one is the Lord once again. And so the two who come running back from Emmaus say to the rest, “The Lord has really risen!”
And so Peter can say on the Day of Pentecost, in reference to the resurrected Jesus, “God has made him both Lord and Messiah, this Jesus whom you crucified.”
The resurrection is an enthronement. It is the heavenly reinstatement of what Jesus showed forth and then set aside while on the earth.
Peter says in that same sermon in Acts 2: “Jesus was a man testified to by God through signs and wonders.” The Lord Jesus was acting on the power and authority of the Lord God. And was rejected: finally rejected by even his closest followers, he walks through the passion narrative as simply “Jesus,” as the messianic pretender.
But God witnesses to him again by the resurrection, enthroning him as the Lord once more. The missing body is not simply the body of Jesus. It is, once again, the body of the Lord.
