The idea of the human Jesus now being in heaven, in his thoroughly embodied risen state, comes as a shock to many people, including many Christians. Sometimes this is because many people think that Jesus, having been divine, stopped being divine and became human, and then, having been human for a while, stopped being human and went back to being divine (at least, that’s what many people think Christians are supposed to believe). More often it’s because our culture is so used to the Platonic idea that heaven is, by definition, a place of “spiritual,” nonmaterial reality so that the idea of a solid body being not only present but also thoroughly at home there seems like a category mistake. The ascension invites us to rethink all this; and, after all, why did we suppose we knew what heaven was? Only because our culture has suggested things to us. Part of Christian belief is to find out what’s true about Jesus and let that challenge our culture.

This applies in particular to the idea of Jesus being in charge not only in heaven but also on earth, not only in some ultimate future but also in the present. Many will snort the obvious objection: it certainly doesn’t look as though he’s in charge, or if he is, he’s making a proper mess of it. But that misses the point. The early Christians knew the world was still a mess. But they announced, like messengers going off on behalf of a global company, that a new CEO had taken charge.

What happens when you downplay or ignore the ascension? The answer is that the church expands to fill the vacuum. If Jesus is more or less identical with the church—if, that is, talk about Jesus can be reduced to talk about his presence within his people rather than his standing over against them and addressing them from elsewhere as their Lord, then we have created a high road to the worst kind of triumphalism.

Only when we grasp firmly that the church is not Jesus and Jesus is not the church—when we grasp, in other words, the truth of the ascension, that the one who is indeed present with us by the Spirit is also the Lord who is strangely absent, strangely other, strangely different from us and over against us, the one who tells Mary Magdalene not to cling to him—only then are we rescued from both hollow triumphalism and shallow despair.

Conversely, only when we grasp and celebrate the fact that Jesus has gone on ahead of us into God’s space, God’s new world, and is both already ruling the rebellious present world as its rightful Lord and also interceding for us at the Father’s right hand—when we grasp and celebrate, in other words, what the ascension tells us about Jesus’s continuing human work in the present—are we rescued from a wrong view of world history and equipped for the task of justice in the present. Get the ascension right, and your view of the church, of the sacraments, and of the mother of Jesus can get back into focus.

There is no need to doubt the literal nature of Christ’s ascension, so long as we realize its purpose. It was not necessary as a mode of departure, for ‘going to the Father’ did not involve a journey in space and presumably he could simply have vanished as on previous occasions. The reason he ascended before their eyes was rather to show them that this departure was final.  He had now gone for good, or at least until his coming in glory.  So they returned to Jerusalem with great joy and waited – not for Jesus to make another resurrection appearance, but for the Holy Spirit to come in power, as had been promised.

—Understanding the Bible, 103.

It is a pity that we call it ‘Ascension Day’, for the Bible speaks more of Christ’s exaltation than of his ascension. This is an interesting avenue to explore. The four great events in the saving career of Jesus are described in the Bible both actively and passively, as deeds done both by Jesus and to Jesus. Thus, we are told with reference to his birth both that he came and that he was sent; with reference to his death both that he gave himself and that he was offered; with reference to his resurrection both that he rose and that he was raised; with reference to his ascension both that he ascended and that he was exalted. If we look more closely, we shall find that in the first two cases, the active phrase is commoner: he came and died, as a deliberate, self-determined choice. But in the last two cases, the passive phrase is more common: he was raised from the tomb and he was exalted to the throne. It was the Father’s act.
