Jamieson, Fausset and Brown on 2 Corinthians 3:1

CHAPTER 3

2Co 3:1-18. The Sole Commendation He Needs to Prove God's Sanction of His Ministry He Has in His Corinthian Converts: His Ministry Excels the Mosaic, as the Gospel of Life and Liberty Excels the Law of Condemnation.

1. Are we beginning again to recommend ourselves (2Co 5:12) (as some of them might say he had done in his first Epistle; or, a reproof to "some" who had begun doing so)!

commendation--recommendation. (Compare 2Co 10:18). The "some" refers to particular persons of the "many" (2Co 2:17) teachers who opposed him, and who came to Corinth with letters of recommendation from other churches; and when leaving that city obtained similar letters from the Corinthians to other churches. The thirteenth canon of the Council of Chalcedon (A.D. 451) ordained that "clergymen coming to a city where they were unknown, should not be allowed to officiate without letters commendatory from their own bishop." The history (Ac 18:27) confirms the existence of the custom here alluded to in the Epistle: "When Apollos was disposed to pass into Achaia [Corinth], the brethren [of Ephesus] wrote, exhorting the disciples to receive him." This was about two years before the Epistle, and is probably one of the instances to which Paul refers, as many at Corinth boasted of their being followers of Apollos (1Co 1:12).
