2 Corinthians 9:15

Ac Valentiniani quidem, qui desuper ex divinis emissionibus deduxere conjugationes, acceptum habent matrimonium: Basilidis autem sectatores, “Cum interrogassent, inquiunt, apostoli, nun sit melius uxorem non ducere, dicunt respondisse Dominum: ‘Non omnes capiunt verbum hoc. Sunt enim eunuchi alii a nativitate, alii vero a necessitate.’” Hoc dictum autem sic interpretantur: “Quidam ex quo nati sunt, naturaliter feminam aversantur, qui quidem hoc naturali utentes temperamento, recte faciunt, si uxorem non ducant. Hi, inquiunt, eunuchi sunt ex nativitate. Qui autem sunt a necessitate, ii sunt theatrici exercitatores, qui, gloriæ studio retracti, se continent.

But why in the fashion of a dove? Gentle is that creature, and pure. Forasmuch then as the Spirit too is “a Spirit of meekness,” He therefore appears in this sort. And besides, He is reminding us of an ancient history. For so, when once a common shipwreck had overtaken the whole world, and our race was in danger of perishing, this creature appeared, and indicated the deliverance from the tempest, and bearing an olive branch,published the good tidings of the common calm of the whole world; all which was a type of the things to come. For in fact the condition of men was then much worse, and they deserved a much sorer punishment. To prevent thy despairing, therefore, He reminds thee of that history. Because then also, when things were desperate, there was a sort of deliverance and reformation; but then by punishment, now, on the contrary, by grace and an unspeakable gift. …
