By the grace of God, during my sojourn at seminary, I was assigned by one of my professors (although I didn't consider it a blessing at the time) to read and report on a little book by a German theologian named Oscar Cullmann. The book was entitled Baptism in the New Testament. Now, the writings of German theologians quite often are difficult for me to understand, sometimes because of linguistic problems in the translation, and sometimes just because their logic escapes me. Not so in this circumstance. This little book was a God send. In it, Dr. Cullmann not only acknowledges the difficulty in understanding why Jesus submitted to a baptism of repentance. He also offers a simple explanation for it, one that had for some reason eluded me.
I had dived deeply into the pool of the intellect searching for an answer that was floating in plain view on the surface. Cullmann says, "It was not a baptism of repentance for HIS sin; it was a baptism of repentance for MY sin, and yours. Just as Jesus died on the cross, not for his own sin, but for yours and mine, so also was he baptized in solidarity with, and on behalf of, you and me."
By this act of going to John to be baptized, by this act of joining people who were acknowledging that their lives were totally messed up and empty and uncertain and in need of a fresh start, Jesus publicly demonstrated the meaning of Emmanuel. God is with us; God has come to us; God has joined us in this world, in our human condition, in our human predicament. God understands! God knows what life and death are really like for you and me!
