EVAGRIUS OF PONTUS:
To those who have entered into the church of the mind and marvel in contemplation of what has come into being, the text says, Do not think that this is the ultimate end or that these are the promises that have been stored up for you. For all these things are [only] vanity of vanities before the knowledge of one’s God. For, just as it is futile for medicine [to seek] a final cure, so is it useless [to seek] after knowledge of the Holy Trinity in the ideas of the [present] ages and worlds.
