On The Pinnacle of The Temple

Et stauit eum supra pinnaculum templi... Cogitavit enim apud se: si miserit se per aerem, scio quoniam est Filius Dei: sine dubio enim mittet se, ut cognoscatur quod est; si autem non potuerit se mittere, scio quoniam homo est. Sicut ergo concupiscentia vanae gloriae ipse ruit de caelo: nam cum esset angelus, volens se ostendere Deum, perdidit et illud quod erat, dum voluit apparere quod non erat: sic putavit et Christum concupiscentia vanae gloriae ferri. Nam sicut difficile aliquem suspicatur mlaum, qui ipse est bonus: sic difficile aliquem suspicatur bonum, qui ipse est malus. Opus Imperfectum in Matthaeum, Homilia V Source: Migne PG 56.666

And he set Him on the pinnacle of the temple... 1 The devil thought to himself: If he bears himself up in the air I will know he is the son of God, for without doubt by bearing himself so it will be known what he is, and if he is not able to bear himself up, I will know he is a man. As, therefore, because of a desire for vainglory he fell from heaven when he was an angel, and wishing to show himself God he destroyed what he was, in wishing to appear as what he was not, so he thought Christ bore the desire for vainglory. For as it is difficult for a good man to suspect evil, so it is difficult for an evil man to suspect good. Opus Imperfectum on Matthew, from Homily 5 1 Mt 4.5
