§.VIII PRIUS: Invariata 1531 vs Variata Art. X — "exhibeantur" presupposes and says more than "adsint & distribuantur"
The first point is plain once you set the two forms of Article X side by side.
In the 1531 Variata — commonly called the Invariata — it runs: Concerning the Lord's Supper they teach that the body and blood of Christ are truly present and are distributed to those who eat in the Lord's Supper, and they reject those who teach otherwise.
In the Variata commonly so named it sounds: Concerning the Lord's Supper they teach that the body and blood of Christ are truly exhibited to those who eat in the Lord's Supper.
I appeal to anyone's sense: do these two propositions differ in substance?
The later wording not only presupposes the earlier — for if Christ's body and blood are truly exhibited in the Supper, then by that very fact they must be said to be truly present there and distributed — but also says more.
Body and blood can truly be present in the Supper, and truly distributed by the minister, and yet not truly exhibited to the communicants — certainly not to all.
But whenever in the holy Supper the minister truly exhibits Christ's body and blood to the communicants, they must both be present and be distributed.
Latin
PRIUS patet ex verbis Articuli Xmi utriusque Confessionis inter se collatis, quae in Variata Anni 1531., communiter Invariata dicta, ita se habent: De Coena Domini docent, quod Corpus & Sanguis Christi verè adsint & distribuantur vescentibus in Coena Domini, & improbant secus docentes; In Variata autem vulgò dicta, sic sonant: De Coena Domini docent, quod Corpus & Sanguis Christi verè exhibeantur vescentibus in Coena Domini. Ubi meritò ad cujusvis Sensum & Intellectum provoco: Num duae dictae propositiones substantialiter inter se differant, praesertim quando posterior non tantum priorem supponit: (Corpus enim & Sanguis Christi dicta verè exhiberi in Coena, eô ipsô necesse est dici verè in Coena adesse & distribui); sed & posterior priori plus dicit: Nam adesse in Coena Corpus & Sanguis Christi verè possunt, nec non a ministro verè distribui, ut tamen non verè, communicantibus, certè non omnibus, exhibeantur; at, quandocunque in S. Coena à Ministro Corpus & Sanguis Christi communicantibus, verè exhibentur, necesse est & ea adesse, & ea distribui.
