Origen

(tom. xix. in Joan. s. 5.) Beneath, and, of this world, are different things. Beneath, refers to a particular place; this material world embraces different tractsd, which all are beneath, as compared with things immaterial and invisible, but, as compared with one another, some beneath, some above. Where the treasure of each is, there is his heart also. If a man then lay up treasure upon earth, he is beneath: if any man lay up treasure in heaven, he is above; yea, ascends above all hearers, attains to a most blissful end. And again, the love of this world makes a man of this world: whereas he who loveth not the world, neither the things that are in the world, is not of the world. Yet is there beyond this world of sense, another world, in which are things invisible, the beauty of which shall the pure in heart behold, yea, the First-born of every creature may be called the world, insomuch as He is absolute wisdom, and in wisdom all things were made. In Him therefore was the whole world, differing from the material world, in so far as the1 scheme divested of the matter, differs from the subject matter itself. The soul of Christ then says, I am not of this world; i. e. because it has not its conversation in this world.
