For I betroth you to one Man, To present a pure a virgin to Christ. 2: Corinthians 11:2
(Like Eve was presented to Adam) She had been taken out of him, was pure when given to Adam.
Now I fear lest somehow, as the serpent deludes Eve by its craftiness, it should be corrupting your minds from the singleness and purity which is in Christ. 2 Corinthians 11:2-3
It was the minds of these believers that were being swayed to corruption by false teachings, by others who were from another spirit that they had not obtained, by a different evangel that they did not receive from Paul.
For if, Indeed he who is coming is proclaiming another Jesus whom we do not proclaim, are you are obtaining a different spirit, which you did not obtain, or a different evangel, but you did not receive you are very with him ideally. 2 Corinthians 11:4
These false apostles, deceitful workers, disguised themselves as a apostles of Christ. 2 Corinthians 12:13
And no wonder, For even Satan disguises himself as an angel of light.
Therefore it is not surprising if his servants also disguise themselves as servants of righteousness who's and end shall be according to their deeds.
The believers were being treated like slaves, (this is not Christ) taking away their substance, devours them,
2719 katesthíō (from 2596 /katá, "down," intensifying 2068 /esthíō, "eat") – properly, eat all the way down; (figuratively) utterly devour, leaving nothing; ferociously consume all the way down, i.e. with a rapacious, voracious appetite – leaving only ruination, without hope of recovery (or even remains).
Takes advantage of you; These false apostles took from the generosity of the Corinthians.
to lay hold by aggressively (actively) accepting what is available (offered). 2983 /lambánō ("accept with initiative") emphasizes the volition (assertiveness) of the receiver.
These people exalted, inflated, themselves, as if they were so far above Paul.
They may have preached Christ out of pretense but used it as a disguise to corrupt these Corinthians and they were taking everything from them and making them slaves to them and not Christ. These believers not only tolerated but actually relished such treatment. This is not Christ.
Paul was just the opposite of these false apostles, he served them like a slave, never took their money, or anything from them, and he was humble before them.
The Corinthian's had a natural bent towards the pride of man, Paul may of been so humble in their site that they looked down upon him, he also was not a great speaker and he goes on later in his letter to defend himself so they have something to boast about in him as their apostle.
And even after the surpassing greatness of the revelations a thorn in the flesh was given to him a messenger of Satan To keep from exulting himself. Here again we see the difference between you two apostles, one fake and one true. The false apostles made it about themselves.
2 Corinthians 4:5 For we preach not ourselves, but Christ Jesus the Lord; and ourselves your servants for Jesus' sake. ...
The evangel that Paul made known to the Corinthian's in which they he had received, and in which they also accepted is stated again in 1Corinthians 15 :3
It is concerned with Christ, With his death, burial, and resurrection.
Remember Saul who was a murder and a persecutor and the Corinthians had a background a pagan practices.
Both sinners made pure through the cross of Christ alone.
Because of Christ alone they were made pure because of the death burial and resurrection of Christ alone. They had been united together with Christ in His his death burial and resurrection. That is the gospel that is free and nothing needs to be added to make one complete in Christ.
This is the gospel they accepted and Paul is correcting the where they had erred in love.
