1 Korintus 3:2

3:2 I fed you milk, ¹  not solid food, for you were not yet ready. In fact, you are still not ready,

1 Korintus 4:10

4:10 We are fools for Christ, but you are wise in Christ! We are weak, but you are strong! You are distinguished, we are dishonored!

1 Korintus 7:10

7:10 To the married I give this command – not I, but the Lord ²  – a wife should not divorce a husband

[3:2]  ¹ sn Milk refers figuratively to basic or elementary Christian teaching. Paul’s point was that the Corinthian believers he was writing to here were not mature enough to receive more advanced teaching. This was not a problem at the time, when they were recent converts, but the problem now is that they are still not ready.

[7:10]  ² sn Not I, but the Lord. Here and in v. 12 Paul distinguishes between his own apostolic instruction and Jesus’ teaching during his earthly ministry. In vv. 10-11, Paul reports the Lord’s own teaching about divorce (cf. Mark 10:5-12).
