So Luther completely rejected the idea that the Divinity of Christ is separated from His humanity in Heaven, Even in Heaven, the Divinity and humanity of Christ belong together. He expresses this in the profound and fantastic doctrine of the ubiquity of the body of Christ the omnipresence of the body of the ascended Christ.
“Christ is present in everything, in stone and fire and tree, but for us He is present only when he speaks to us through everything. Now this is the idea that God drives toward embodiment, towards corporeity. and that the omnipresence of the body of Christ m the world is the form in which God’s eternal power is present in the world. Now if you want to carry this through in scholastic terms, namely taking it literally or superstitiously, then it is an absurd doctrine because it belongs to a body to be circumscribed. But if you take it symbolically, then it is a profound doctrine because it says that if God is present in anything on earth He is always also present with His concrete historical manifestation, namely with Christ.
Now Luther meant that much more primitively, but his meaning is that in every natural object you can have the presence of the Christ. And in a Lutheran service during the Sundays in Spring, you always find a tremendous amount of f lowers and nature brought into the church, because of this symbol of participation of the body of Christ in the world.
Now what kind of principles are involved in this discussion? When it came to an end, all the Reformers agreed that they denied the; transubstantiation doctrine and agreed about a lot of points about the Lord’s Supper, but they did not agree about the ubiquity, I. e., the presence of Christ everywhere. This means there is a fundamental difference, which Luther stated when he left the castle of Wittenberg: “They have not the same spirit with us.” What did this mean? First of all, it is the relationship between the spiritual and the bodily existence. In Zwingli you have the humanist intellectualism separating the spirit from the body, and ultimately the Neoplatonic background of this. Therefore in Calvinism there is a lack of interest in the problem of expression. But for Luther, spirit is only present in its expressions; it is directly present in consciousness which finally led to the amalgamation with Cartesian ideas.
