Communication of properties is reciprocal naming of either nature for the whole person, and is as real as the union
Or even what they call the communication of properties — that is, of either nature's properties and workings in the one person where the natures are united, and that as a two-way exchange (κατὰ τρόπον ἀντιδόσεως).
By it the names, properties, and operations of either nature — say the divine — are truly and really said of the whole person, and that person is sometimes named from the humanity (John 3:13), and the other way round, as in Acts 20:28 and 1 Corinthians 2:8, examples ready in Holy Scripture.
That communication, on the account just given, is as real as the natures' union is real; though the speaking leans toward synecdoche, where what belongs to the part is given to the whole according to that part.
The theologians already named have set this out at length.
Latin
Vel etiam Communicationem (quam vocant) Idiomatum, idest, proprietatum & operationum alterutrius Naturae, in eadem Persona in qua Naturae unitae sunt, eamque reciprocam, κατὰ τρόπον ἀντιδόσεως: Qua scil. Nomina, Proprietates, & Operationes alterutrius Naturae, puta Divinae, praedicantur vere & realiter de tota Persona eaque nonnunquam ab Humanitate denominata, Joh. III. 13. & vicissim ut Act. XX. 28. 1. Cor. II. 8. obviis in Scriptura S. exemplis. Quae Communicatio (ex dictis modo) tam realis est, quam est realis Unio Naturarum; licet modo loquendi ad Synecdochen accedat, qua quod Partis est, tribuitur Toti, secundum illam Partem. Sed haec fuse dicti Theologi.
