Peter and the Lightning

Sic Petrus, cum, sanato homine qui claudus ex utero matris fuerat, signum fecit quod omnes qui cognoscerent valde mirarentur, dixit: Quid miramini in hoc, aut nos quid intuemini, quasi nostra virtute aut potestate fecerimus hunc ambulare? Deus Abraham, Deus Isaac, et Deus Jacob, Deus patrum nostrorum glorificavit Filium suum Jesum. Et paulo post: In fide nominis ejus hunc quem vidistis et nostis, confirmavit nomen ejus. Signum quippe faciens, intuentium oculos miraculi lumine perstrinxit; sed humilitatem custodiens, et laudem auctori reddens, quasi unde venerat rediit, quia lux fulguris unde fuerit ostendit. Sancta itaque animalia cum ad signa operanda veniunt, et cum ad reddendam auctori suo gloriam intus apud semetipsa redeunt, fulgur sunt, quia et ostendendo miracula, et exempla humilitatis praebendo, mentes intuentium feriunt et incendunt. Sanctus Gregorius Magnus, In Ezechielem Prophetam, Liber Primus, Homilia V

So Peter says, with the healing of the man who was lame from his mother's womb, a sign made that all who understand greatly admire, 'Why do you wonder at this, or why do you gaze at us, as if by our own power or our own ability we have made this fellow walk? The God of Abraham and Isaac and Jacob, the God of our fathers has glorified His son Jesus.' 1 And a little after: 'In the faith of His name this which you see and know, confirms His name.' 2 A sign is certainly is made, striking the eyes of onlookers with the light of a miracle, but guarding humility, praise is returned to its Creator, as if returning it from where it came, as light of lightning shows where it came from. Thus holy creatures when they come to the working of signs, and when they have returned to the Creator of it the glory of it and to themselves return, are as lightning, because in the showing of miracles, and in the expression of humility, the mind of onlookers they catch up and cast down.
