The other questions related to church meetings for the "Lord's supper" and the exercise of "spiritual gifts." They give opportunity for the development of Paul's noble doctrine of unity through loving service (xi. 2--xiv. 40). The doctrinal section of 1st Corinthians concludes with a full statement of Paul's doctrine of the resurrection body (called forth by Greek objections to the Jewish). From the items of business at the close we learn that "the collection for the saints" has been under way some time already "in Galatia," and that Paul hopes, after passing through Macedonia, to join the delegation which is to carry the money to Jerusalem (xvi. 1-6). As it turned out Paul actually followed the itinerary outlined in 1st Cor. xvi. 1-6, but not until after distressing experiences. Timothy, sent (by way of Macedonia, Acts xix. 22) as Paul's representative (iv. 17; xvi. 10 f.), was unable to restore order. The opposition to Paul's apostolic authority, treated almost contemptuously in ix. 1-14, grew to alarming proportions. Paul received so direct and personal an affront (either on a hasty visit undertaken in person from Ephesus, or in the person of Timothy) that he despatched a peremptory ultimatum, whose effect he is anxiously waiting to hear when 2nd Corinthians opens with Paul driven out from Ephesus, a refugee in Macedonia (_c._ 55). It is highly probable that the disconnected section appended between 2nd Cor. ix. 15 and the Farewell, is taken from this "grievous" letter written "out of much affliction and anguish of heart with many tears" (2nd Cor. ii. 1-4; vii. 8-16); for it was not only a peremptory demand for punishment of the offender, but also a letter of forced self-commendation. Paul cannot have written in self-commendation on more than one occasion, and he promises not to repeat this in iii. 1 ff. We may take 2nd Cor. x.-xiii., then, as representing the "grievous" letter. The opposition emanates from Judaizers who say they are "of Christ," and may therefore be identical with those of 1st Cor. i. 12. But it has grown to proportions which for a time made Paul despair of the church's loyalty. Titus' arrival in Macedonia with news of their restored obedience had been an inexpressible relief (ii. 5-17; vii. 8-16). It remains only to set his 'ministry of the new covenant' once more in contrast with the Mosaic 'ministry of condemnation and death,' including further elucidation of the doctrine of the resurrection body (iii. 1--vi. 10) and to urge generosity in the matter of the collection (chh. viii.-ix.).
