Visions and Weakness

Fili hominis, vide oculis tuis, et auribus tuis audi. Ad testimonium spiritalium rerum deducto, quid est quod cum dicitur: Vide oculis, additur tuis, et cum subditur Audi auribus, adjungitur tuis? Sed sciendum quia oculi atque aures corporis adsunt etiam carnalibus, eisque sunt in usu rerum quae corporaliter videntur. Oculi vero atque aures cordis solummodo spiritalium sunt, qui invisibilia per intellectum vident, et laudem Dei sine sono audiunt. Has omnipotens Dominus aures quaerebat, cum diceret: Quis habet aures audiendi audiat. Quis namque in illo populo esse tunc poterat, qui aures corporis non haberet? Sed cum dicitur: Qui habet aures audiendi audiat, aperte monstratur quod illas aures quaereret quas omnes habere non poterant. Dicatur ergo: Fili hominis, vide oculis tuis, et auribus tuis audi. In priori autem locutionum nostrarum parte jam diximus cur propheta, quoties ad videnda spiritalia ducitur, filius hominis appellatur. Sed ne hoc mente excesserit, breviter replico, quia hac appellatione memoratur semper quid est ex infirmitate, ne extollatur de contemplationis magnitudine. Et notandum quia diversa sunt ut dicatur, Oculis tuis vide, auribus tuis audi, et tamen filius hominis vocetur. Sed per haec verba quid ei aliud aperte dicitur, nisi, spiritalia spiritaliter aspice, et tamen carnales infirmitates tuas memorare? Sanctus Gregorius Magnus, In Ezechielem Prophetam, Liber Secundus, Homilia II

Son of man, see with your eyes, and hear with your ears. 1   To the spiritual testimony of things let us attend. What is this which is said: 'See with eyes,' with the addition of 'your,' and then after it, 'Hear with ears,' with 'your' again joined to it? But it must be known that the eyes and the ears of the body are part of the corporeal body and that of them is the use of seeing things material. Truly the eyes and the ears of the heart alone are spiritual, which gaze on invisible things through the intellect, and which without sound hear the praise of God. These are the ears the omnipotent Lord asks for, when He says, 'He who has ears for the hearing, let him hear.' 2 For who in that people  was not able to hear who had corporeal ears? But when He said, 'He who has ears for the hearing, let him hear'  it is obvious that He seeks that which not everyone has. Thus it is said, 'Son of man, see with your eyes, and hear with your ears.' In our previous speeches we have spoken about why the prophet, being led to the contemplation of spiritual things, was named son of man. But lest the mind have wandered, I shall briefly repeat that his title is a reminder always that he is in a state of weakness, and that he should not be carried away by contemplation of greatness. And let the differences be noted, when it is said 'See with your eyes and hear with your ears,' and then when he is called son of man. For by these words what is said to him, unless that spiritually seeing spiritual things, he be mindful of his corporeal weakness?
