[This letter is from] Paul, who was called by the will of God to be an apostle of Jesus Christ, and [from] our brother Sosthenes;

And I did not use persuasive words of [human] wisdom in my message and preaching, but they were [accompanied by] a demonstration of the Holy Spirit and power [from God]. [Note: This "demonstration" could have included the evidence of miraculous spiritual gifts which Paul utilized while there in Corinth. See 14:18].

Get rid of the old yeast [i.e., of sin, and especially the unrepentant sinner], so that you can be a new batch of dough, without yeast in it [i.e., a godly church without unrepentant sinners in it] as [I know] you really are. For our Passover [Lamb], Christ, has already been sacrificed.

But I wrote to you not to associate with anyone claiming to be a [Christian] brother who is [guilty of being] sexually immoral, or greedy, or an idolater, or who speaks abusively, or a drunkard, or a swindler. Do not even eat [a social meal] with such a person.

Was any man already circumcised when he was called [by God to be a Christian]? Then he should not [try to] become uncircumcised. [Note: Some Jews in that day resorted to a surgical procedure in an attempt to conceal their circumcision]. Was any man uncircumcised when he was called? Then he should not become circumcised.

Brothers, each person should remain [in fellowship] with God in the [same] state he was in when he was called [by God to be a Christian].

A wife is bound [i.e., to stay married] for as long as her husband is alive. But if her husband dies, she is free to be married to anyone she wants; [but it must be] only in the Lord [i.e., he must be a faithful Christian].

I now want to reply to the matter of idolatrous sacrifices [which you wrote to me about]. We know that we all possess knowledge. [Note: This may be a statement posed to Paul by the Corinthians, who seemed quite preoccupied with "knowledge"]. Knowledge [only] makes people arrogant, while love builds them up [spiritually].

For I want you to be [fully] aware, brothers, that our forefathers were all under the cloud, and all of them passed [safely] through the [Red] Sea. [Note: This refers to God guiding the Israelites through the desert during the daytime by a cloud moving along above them . See Ex. 13:21-22].

And if all the parts were one part, how could there be a [whole] body?

And what you yourself sow is not the plant that will [eventually] come up, but simply a seed. It may be a grain of wheat or something else.
