Context

“Therefore He will be seen by all in one way only; and therefore He will not be seen more perfectly by one and less perfectly by another. Obj. 2: Further, Augustine says (Octog. Tri. Quaest. qu. xxxii) : "One person cannot see one and the same thing more perfectly than another." But all who see the essence of God, understand the Divine essence, for God is seen by the intellect and not by sense, as was shown above (A. 3) . Therefore of those who see the divine essence, one does not see more clearly than another.” source
