There's a rich footnote in Alexandra Brown's The Cross and Human Transformation: Paul's Apocalyptic Word in 1 Corinthians that details the dense perceptual language in 1 Corinthians 1-2.

I find this list illuminating as it helps map out a large semantic territory. And what it helps illustrate, to the point of this series, is the epistemological nature of the gospel.
Why would that be of interest?
It's of interest to me because of how we tend to moralize the gospel. Christian life is about moral living. And it is that. But seeing comes before doing, knowing before moral action. Consequently, my interest in the rich matrix of perceptual and epistemological words listed above is that I think something primary is at stake, something prior to moral considerations. For how can you take proper action in the world if you're blind, lost, deluded, ignorant, or confused? As Jesus said, the blind end up leading the blind and everyone falls into the pit. Sight is required for navigation.
Let me give concrete example of what I'm driving at. When we survey the moral failures of the church are these, at root, moral failures, failures to do the right thing? Or are we witnessing something deeper and more fundamental, a confusion about the very nature of the gospel? (I'm not talking about moral failures of pastors, but moral failures of churches, whole groups of Christians and denominations getting wildly off track from the gospel.) We see evidence of both, of course. But my point in asking the question is that when we see Christians behaving badly what we're often witnessing are epistemological failures of the sort Paul is describing in 1 Corinthians. The problem is less about failing to live up to Christ than a complete misperception of Christ. And when Christ is misperceived all sorts of bad things soon follow.
That is one of my favorite passages and I don't pretend to have penetrated anywhere close to its depth, so I will save that list of words!
I do question whether 'epistemology' is the right word, here. I worry that it doesn't really map onto what the Tanakh means by 'heart' (where Deut 6:5 MT has 'heart', the LXX has 'mind'), nor what is targeted by μετάνοια (metanoia) in the NT. Even the word 'repentance' is iffy; meta-noia means change-in-thinking. But I would be wary of thinking that Paul was completely enraptured by the Greeks' ideal of contemplation; I'll bet he would have said that he is talking about that same 'heart' we see here:
The heart of a person will plan his ways,
and YHWH will direct his steps.
(Proverbs 16:9)
Some translations actually translate leb as 'mind', but I think that's iffy. It makes an 'epistemological' reading too easy, when the ancient Hebrews would have chosen something far more like "seat of the understanding". One's desires come from one's leb. One's desires do not come from one's epistemology.
If you grant me the above, then instead of saying that some churches have "a complete misperception of Christ", we could instead talk about disordered desires. When it gets really bad, Ezekiel 34 can describe both the leaders and the followers. And if we take Luke 12:54–59 and 1 Corinthians 6:1–11 into account, the very notion of a leader/follower dichotomy becomes difficult. How many people call a member in their congregation 'Pastor', over against Jesus' words in Matthew 23:8–12? How much 'lording it over' and 'exercising authority' over do we see among Christians, over against Jesus' words in Matthew 20:20–28? It is almost as if we have perverted the very notions of 'servant' and 'service', such that extant social hierarchies remain rather unchallenged …
