There have come forward in our day those who have said that a symbolical meaning is to be found in the word “This.” I commend their faith, if only it is not counterfeit. For God seeth the heart, we poor wretches judge from the face [1 Sam. 16:7]. I greatly commend, therefore, not the faith which makes them venture thoughtlessly to treat these words, but that through which they see that it is untenable for us to understand bodily flesh here. I will not, however, speak now of the Charybdis the fear of which drove them upon this Scylla, for it has no bearing upon this matter.*
Those who have come forward to whom Zwingli refers are, among others, Matt Alber. On 16 November of 1524 Zwingli addressed him thusly:
Gratia et pax a domino! Aspersit nos rumor de certamine, quod tibi futurum est cum quodam fratre, ut aiunt, ingenue etiam Christo favente, qui ut facie mihi notus est, ita nomine ignotus, contra tu nomine nobis et euangelii gloria notissimus es, facie ignotus. Certamen autem Michael noster audivit περὶ τῆς εὐχαριστίας esse indictum, in qua vereor multos vehementer errare, nisi ego magis quam omnes errem. Ac nisi me fallit omnis scripturae tum proprietas, tum sensus, imo pietas ipsa, longe hactenus a scopo iecimus. Quisquis autem peccati huius tandem sit autor, nunc non est ut dicam per epistolam, quam esse brevem oportet.
And then he rips into Carlstadt. Good times, good times.
