Kierkegaard’s contrast between Jesus and the older son in the parable of the Prodigal Son.
In this gospel the prodigal son has an older brother; but he will do nothing to save the prodigal. But Christianity itself is, indeed, κατεξοχήν the gospel. And in this gospel the prodigal son (the human race) has an older brother (the only begotten Son) and he does everything, loses his life in order to save the prodigal, in agreement with the father on this from the beginning.
