1 Corinthians Three
But why does Paul raise the question of a letter of recommendation at all? We have to assume that the fact that he did not bring such a letter with him to Corinth had been used as a basis of criticism by someone in the church. Quite likely it was the offender (the one who caused pain, 2:5; who did wrong, 7:12) who, in mounting his personal attack against Paul, criticized the apostle’s lack of such a letter. In so doing the offender probably received moral support at least from the ‘false apostles’ who had already infiltrated the church and were themselves to oppose Paul so vehemently later on (as reflected in chs. 10–13).
Are we beginning to commend ourselves again?
Others had come to Corinth with letters (e.g. Apollos, cf. Acts 18:24–28) because they needed them. It is absurd that anyone should require Paul to bring such letters to the Corinthian church when he was its founding apostle.
You yourselves are our letter of recommendation
If the Corinthians are Paul’s letter of recommendation, the author of that letter is Christ. Thus Paul claims that no-one less than the exalted Lord has produced this letter for him. But while Christ is the author of the letter, Paul says it was delivered by us. The word delivered is a translation of diakonētheisa, which literally means ‘ministered’ or ‘serviced’. Within a metaphor of letter writing (as here) where an author and a scribe are envisaged, a better rendering would be ‘enscribed’. So Paul sees the Corinthians as a ‘living letter’ dictated by Christ, but ‘enscribed’ by Paul through the apostolic ministry of gospel proclamation.
Paul further describes his confidence by saying that it is God who has made us competent to be ministers of a new covenant. The expression new covenant is found in only one other place in Paul’s writings, i.e. in 1 Corinthians 11:25, where it forms part of the Lord’s Supper tradition which Paul says he received (‘This cup is the new covenant in my blood’). This use of the term by Paul makes it plain that he, like the writer to the Hebrews (cf. Heb. 9:15–28), saw the death of Christ as that which established the new covenant. However, what Paul stresses in the present context is that the ministry of the new covenant is one which is not in a written code but in the Spirit (lit. ‘not of letter but of Spirit’).
However, the ministry of the Spirit is quite different. It is a ministry of the new covenant under which sins are forgiven and remembered no more, and people are motivated and enabled by the Spirit to do what the improper application of the law could never achieve (cf. Jer. 31:31–34; Ezek. 36:25–27; Rom. 8:3–4).
In 3:7–18 the apostle, by means of an exposition of Exodus 34:29–32 and then of 34:33–35, further compares and contrasts the ministries of the new and old covenants so as to demonstrate the superiority of the former. Paul’s primary purpose in so doing is to highlight the glorious character of the ministry with which he has been entrusted and so explain why, despite so many difficulties, he does not lose heart (cf. 4:1).
The superiority of new covenant is argued on three counts: (a) the ministry of the Spirit is more splendid than the ministry of death, (b) the ministry of righteousness is more splendid than that of condemnation, and (c) the permanent ministry is more splendid than that which fades away.
He also sees in the veiling of Moses’ face something analogous to the ‘veil’ which lay over the minds of many of his Jewish contemporaries who could not properly understand the law of Moses when it was read in their synagogues. Believers, by contrast, are those who with unveiled faces behold the glory of the Lord.
