Conversion is a matter of the heart. See Romans 10:10
Laudetur Iesus Christus.
But what do you think “heart” means?
Greek: καρδία. mind, “ὡς ἄνοον κραδίην ἔχες” Il.21.441; “κραδίη πόρφυρε” Od.4.572; “κραδίη προτιόσσετ᾽ ὄλεθρον” 5.389; “εἰ θεάσῃ τοῖς τῆς καρδίας ὀφθαλμοῖς” Corp.Herm. 4.11, cf. 7.2; διαλογισμοὶ ἀναβαίνουσι ἐν τῇ κ. Ev.Luc.24.38.
Latin: cor. According to the ancients (cf. Cic. Tusc. 1, 9, 18) as the seat of wisdom, understanding, heart, mind, judgment, etc. (most freq. in ante-class. poets): quem (Hannibalem) esse meum cor Suasorem summum et studiosum robore belli, Enn. ap. Gell. 7, 2, 9 (Ann. 374 Vahl.): “Ego atque in meo corde, si est quod mihi cor, Eam rem volutavi,” Plaut. Most. 1, 2, 3 dub. (bracketed by Ritschl): “quantum ego nunc corde conspicio meo,” id. Ps. 3, 1, 3: “quicquam sapere corde,” id. Mil. 2, 3, 65; Ter. Phorm. 2, 2, 7; Lucr. 1, 737; 5, 1107: “nec enim sequitur, ut cui cor sapiat, ei non sapiat palatus,” Cic. Fin. 2, 8, 24 Madv.; cf. id. ib. 2, 28, 91: “stupor cordis,” id. Phil. 3, 6, 16: cor Zenodoti, Fur. Bib. ap. Suet. Gram. 11; cf.: “cor Enni,” Pers. 6, 10; cf., in a play on the meaning, I. A.: si pecudi cor defuisset, Caes. ap. Suet. Caes. 77 fin.
I suggest that this non-sentimental meaning of the word “heart” is more consistent with St. Paul’s reference to justice.
The Greek definition above even cites Luke 24:38 as an example of this meaning of the word.
We are at war with spiritual powers. The warfare is intellectual. We cannot surrender the ground. Conversion and conscience are both acts of reason.
