Thus in these latter words concerning the salutary use of the Supper there is a description of the spiritual eating of the body of Christ which takes place by faith. And just as the substance of the Supper and the salutary use of the same are distinguished, so it is one thing when Christ says: “Take and eat; this is my body,” and another thing when He says: “This do in remembrance of Me,” which takes place by spiritual eating through faith. Thus the sacramental and the spiritual eating are dealt with and described separately. For there is a distinct and clear description of how the substance of the Supper, which consists of the bread and the body of Christ, is received,namely, in the mouths of the participants. This is the sacramental eating … And then there is also a distinct and clear description of how those who participate in the Supper receive it and use it in a salutary way, namely, by faith. This is the spiritual eating. (‘The Lord’s Supper’ [CPH, 1979], 112-113, underlining added)
This is an unhelpful distinction. Or rather, the categories are unhelpful.
To refer to the anamnesis (‘do this in remembrance of me’) as “spiritual eating” has the tendency to drive a wedge between physical and spiritual eating, despite Chemnitz’s eloquent and earnest efforts to the contrary.
Presumably the category of ‘spiritual eating’ as distinct from ‘physical eating’ derives from John 6 where, according to traditional Lutheran (and Reformed) exegesis, Jesus’ words about eating His flesh and drinking His blood refer to spiritual eating in the form of receiving Him and His words in faith.
This category of ‘spiritual eating’ has here been transposed onto the Lord’s Supper, even though I’m not aware of New Testament references to the ‘spiritual eating’ of the Supper.
Is it not the case that Jesus’ words instruct the disciples concerning how they are to eat (physically) His body and blood, namely in faith (“in remembrance of me”)? This is not a twofold eating—physical and spiritual—but a single eating with one of two effects.
The difference between the believer and the unbeliever is not that one eats physically and spiritually while the other eats physically only. The believer eats physically with faith, thereby receiving grace through the physical eating. The unbeliever also eats physically but without faith, thereby receiving condemnation through the same eating.
So there is only one category of eating: physical eating. But there are two categories of reception: in faith to salvation, and without faith to condemnation.
By avoiding the misapplied category of ‘spiritual eating’, we can make a clean break from those who deny the physical eating of the Lord’s body and blood, as well as avoid all sorts of ecumenical ambiguities when dealing with those who thrive in the blurring of lines (e.g. mainstream Anglicans).
Am I missing the mark here?
