One quote from this link says: "The first of these 'errors' [in Tertullian's Apology] is the reading Christo et Deo, given by most of the MSS of the Apology, while Pliny (see above) writes Christo quasi Deo.
Prof. Merrill does well to place little weight on this discrepancy, for, as Lightfoot observes (op. cit. i 57, note), there can be no question that the correct reading is ut. Oehler indeed accepted et, and protested against Scaliger's emendation (followed by Havercamp) as 'contra librorum optimorum et paene omnium fidem.' But the only passage which he adduces in support of the reading which he retains is De Spectac. 25 ἐἰς αἰῶνας ἀπ' αἰῶνος alii omnino dicere nisi Deo et Christo', and here the reversed order is surely decisive against a parallelism."
