Annotatio I §.III (d): Cup is the New Testament in Christ’s blood — many tropes; Valencia / Cajetan
(d) In the other half of the Supper Institution — Luke 22:20 and 1 Cor. 11:25 — The Cup is the N.T. In Christ’s blood.
No one easily denies that one line breathes several tropes — not even Cajetan.
Gregory of Valencia grants the necessity: the cup must be taken for the contained blood, and testament/promise is predicated of that blood only figuratively (as Matthew and Mark’s blood of the New Testament shows).

Denique (d) Cùm in Institutionis S. Coenae parte altera propositio, tùm à Christo primum enunciata, apud Lucam cap. 22. vers. 20. tùm ab Apostolo 1. Cor. 11. vers. 25. repetita, occurrit: Poculum est N. T. in sanguine Christi, unô eam plures tropos spirare nemo facilè inficias ibit, ne quidem Pontificius Cajetanus in Luc. 22. ex Thoma de Aquino 1. Cor. 10.; quin potius Gregorius de Valencia etiam necessitatem tropi agnoscet de Eucharistia Libro I. cap. 9. th. 42. ita scribens: In propositione, Hic calix est N. T. in sanguine meo, oportere prorsus calicem accipi pro re contenta, quae est Christi Sanguis; & consequenter, de hoc sanguine testamentum, seu promissionem, non nisi figurate praedicari, quatenus promissionem videl. & Testamentum confirmat, ut explicat ille dicendi modus Matthaei & Marci in casu nominis obliquo, sanguis Novi Testamenti.
