Annotatio VI §.VII: Indigni eat panem Domini (bread of Lord), not panem Dominum (Lord-bread)
For their sake he names only the lesser object — this bread — “whoever eats this bread unworthily is guilty of the body”; examine yourself, then eat and drink.
So the true head is those who eat unworthily the bread of the Lord, not the bread that is the Lord — clearer than the Author’s Oral-body of the Indigni head.
Latin
Eóque manducationis, in legitimo S. Cœnæ usu, Objectum dimidiatum duntaxat minusque principale, scilicet panem solum, indignorum causâ, inducit, ita scribens: Quoties de pane hoc ederitis & de poculo hoc biberitis, mortem Domini annuntiabitis, donec redeat. Quicunque igitur indignè de PANE HOC manducat, is reus sit Corporis Christi: Indeque exploret Seipsum homo, & ita edat de pane hoc, & bibat de poculo hoc. Nimirum, hoc Doctrinæ caput de Indignorum Manducatione panis istius, qui Domini est, non autem panis illius, qui Dominus ipse est, rectius ac evidentius multo, quam (quod Auctor vult) caput doctrinæ, de Indignorum Manducatione corporis Christi Orali.
