Annotatio IV §.VIII close: Ambrose — after consecration it is Christ’s body; old creature made new — stop before §.IX
How can what is bread be Christ’s body by consecration? By the Lord’s words the sacrament is made — Christ’s speech is operative.
If bread and wine begin to be what they were not and are changed into another, then it was not Christ’s body before consecration, but after it is. He spoke and it was done: you were an old creature; after consecration you begin to be a new one.
Augustine).
Latin
Hoc igitur adstruemus, quomodo qui panis est, potest esse corpus Christi consecratione. Consecratio autem fit verbis Domini, ut venerabile Sacramentum conficiatur. Vides quàm operatorius sit sermo Christi. Si ergo tanta vis est in sermone Domini, ut inciperent esse, (panis & vinum) quæ non erant, & in aliud commutentur, Ergo, ut Tibi respondeam, non erat corpus Christi ante consecrationem, sed post consecrationem jam est corpus Christi. Ipse dixit & factum est; TU IPSE ERAS, SED ERAS VETUS CREATURA; POSTQUAM CONSECRATUS ES, NOVA CREATURA ESSE CŒPISTI.
