[ad. Schol.L. transaccidentātio (Duns Scotus: the attribution to P. Lombardus in Marbeck is a mistake due to confounding commentary with text); after transubstāntiātio.] A transmutation of the accidents of the bread and wine in the Eucharist, as distinguished from transubstantiation, in which the substance alone is changed.
[c. 1300. Duns Scotus, Sent., IV. xi. i. § 3. Transitio accidentis in accidens, magis diceretur transaccidentatio, quam transubstantiatio.]
1581. Marbeck, Bk of Notes, 1101. Long after Boniface the third … did Petrus Lombardus [see above] bring vp these termes of Transmutation, and Transaccidentation.
1861. Pearson, Early & Mid. Ages Eng., 443. Such fables really involve a completely different doctrine, which might be called transaccidentation, but which no church has ever yet deliberately set forth.
1874. Fiske, Cosmic Philos., I. 123, note. The schoolman … asserted that the individuality of the bread (its breadness) was exchanged for the individuality of Christ (his humano-divinity)…. It was a noumenal, not a phenomenal change: the latter would have been [not transubstantiation, but] ‘transaccidentation.’
