Irenaeus

But since he (Paul) has described that assumption of himself up to the third heaven as something great and pre-eminent, it cannot be that these men ascend above the seventh heaven, for they are certainly not superior to the apostle. If they do maintain that they are more excellent than he, let them prove themselves so by their works, for they have never pretended to anything like [what he describes as occurring to himself]. And for this reason he added, "Whether in the body, or whether out of the body, God knoweth," that the body might neither be thought to be a partaker in that vision, as if it could have participated in those things which it had seen and heard; nor, again, that any one should say that he was not carried higher on account of the weight of the body; but it is therefore thus far permitted even without the body to behold spiritual mysteries which are the operations of God, who made the heavens and the earth, and formed man, and placed him in paradise, so that those should be spectators of them who, like the apostle, have reached a high degree of perfection in the love of God.
