There is more to come—there is the fullness. There is coming a day when, as Paul says in Romans 11, the deliverer will come from Zion and “all Israel will be saved.” Not just the current remnant of Messiah-believers, but also those who at the moment reject Jesus. There is a day coming when, as the book of Revelation says, the kings of the earth and all the nations will bring their treasures into the New Jerusalem through its ever-open gates to worship God and the Lamb.
Now we see salvation in part, then we shall see it in full.
So currently we see a division within Israel and the nations between the redeemed and the lost, between the elect according to grace and those who are not, but one day there will be no such division. And then the promises associated with the birth of the Messiah will be filled full, or full-filled.
My second theme can be explained much more simply. Remember that Christmas is also about the incarnation—the Word made flesh, “eternity contracted to a span, incomprehensibly made man.” For the Church, the real and complete humanity of Jesus is really important. The Church Fathers said: “that which has not been assumed has not been healed.” What they meant was that Jesus had to be human to heal our humanity. If he had not taken on our human nature then he could not transform it in himself.
Now Jesus is, of course, a particular human being. He is a real, solid, flesh and blood and bone and spit human individual. But more than that, he is a representative person. As the Messiah of Israel, he represents the whole nation of Israel before God. He is Israel-in-miniature. He embodies its story of exile and restoration in his death and resurrection. In the same way, he is the second Adam—the fountainhead of a renewed human race. In his humanity, he represents all humans before God. The story of humanity in its expulsion from Eden and its subjection to death is played out in his crucifixion. But then his resurrection is not simply about himself—it is on our behalf, the behalf of all of us, Jews and Gentiles. The resurrection of Jesus is the resurrection of humanity in him. It is the future of the world inscribed into the risen flesh of the Son of God. And it is here, in this risen and ascended human being that my hope for universal salvation is grounded. How can we know that God will one day deliver all? Because God has already declared his hand in the resurrection. It has been done—so it will come to pass.
And all this promise was wrapped up in the life of a little human baby in a manger in Bethlehem.
That, at least, is something of what may be a little distinctive about a universalist’s understanding of Christmas.
