Herman Sasse: It is impossible to define Luther’s doctrine as consubstantiation. Even the words ‘in the bread’, ‘with the bread’, ‘under the bread’, or ‘in, with, and under the bread’, were never regarded by Luther as more than attempts to express in these old, popular terms inherited from the Middle Ages the great mystery that the bread is the body, the wine is the blood, as the Words of Institution say**.**Christ say it IS His flesh. Christ says it IS my body. ** How do you get in, within, under out of Christ’s word?**
The word trans… was first used much later. But that does not mean the belief started with the use of the word. Ambrose is clear when he say “nature” is changed. Sacramental union does not mean a change in nature as Ambrose describes.
Please, where is in, within, under even contemplated in the bible or by the Church Fathers.

Sacramental union is an expression, “this is my body” is the doctrine.
Again, Herman Sasse:
***For Luther, the bread is the body in an incomprehensible way; the union between the bread and the body cannot be expressed in terms of any philosophical theory or rational explanation; it is an object of faith, based solely on the words of Christ. **The question which was put to him, not only by Zwingli, but also by his older adversaries, as to how the bread could be called the body of Christ if it still remained bread, was answered by Luther in pointing out the mode of speech called synecdoche. In his great controversy with Carlstadt he had already explained the words ‘This is my body’ as synecdoche. ‘This’ referred to what Jesus held in his hands, the bread, not (as Carlstadt’s impossible exegesis would suggest) to the body to which Jesus pointed. As a mother, pointing to the cradle in which her baby lies, says, ‘This is my child’, or as a man, pointing to a purse, may say, ‘Here is a hundred dollars’, so we say of the bread in a similar way, “This is the body of Christ’. This is a common mode of speech called synecdoche, an abbreviated speech in which the containing vessel is mentioned instead of its content. The objection, especially by Zwingli, that thus Luther himself did not understand the sacramental words literally, but figuratively, was refuted by Luther as not being to the point, because the reality of the body was not denied. In all other figures of speech, the words ‘body’ and ‘blood’ are understood figuratively; the synecdoche takes the reality of the elements as well as the reality of body and blood seriously. *
And Paul does this, as well, using the term bread when discussing Christ’s body.
