Confessional Corner: Person of Christ (Ep VIII)

The Sacramentarians have asserted that the divine and human natures in Christ are united personally in such a way that neither has real communion. This means (in deed and truth) that they do not share with the other nature what is unique to either nature. They share nothing more than the name alone. For they plainly say, "The personal union does nothing more than make the names common." In other words, God is called man, and man is called God. Yet this happens in such a way that the divine has no real communion (that is, in deed and truth) with humanity. And humanity has nothing in common with divinity, its majesty and properties. Dr. Luther and those who agreed with him have contended against the Sacramentarians for the contrary teaching. (Ep VIII 3)
