The Talmud has an interesting contribution, I think, to our understanding of Paul’s little phrase ‘we see through a glass darkly’ when it remarks concerning Isaiah’s claim to have seen the Lord-
‘I saw the Lord’, [is to be understood] in accordance with what was taught: All the prophets looked into a dim glass, but Moses looked through a clear glass. (b. Yeb 49b).
If Rabbinic materials make use of the phrase ‘dim glass’ to describe the fact that none of the prophets really saw God as clearly as Moses did; and Paul uses the same phrase in reference to our own perceptions of God, then it stands to reason that Paul is following a tradition similar to the later Rabbis in which Moses alone saw God and everyone else only gets a dim vision through bad glass.
This has interesting implications for Paul’s supposed exalted Christology, no?
