This long passage has a good many difficulties of detail, for the grammarian and the textual critic. Where it seems necessary, these will be referred to in the notes; but as the large meaning of the writer is hardly affected by them, they need not interrupt the course of exposition. It falls into three parts, which are clearly marked as such in the Revised Version: (1) Chap. viii. 16-24, commending to the Corinthians the three brethren who were to precede Paul and prepare the collection; (2) Chap. ix. 1-5, appealing to the motives of emulation and shame to reinforce love in the matter; and (3) Chap. ix. 6-15, urging liberality, and enlarging on the blessed fruits it yields. The first of these divisions begins, and the last ends, with an exclamatory ascription of thanks to God. (1) Chap. viii. 16-24. Of the three men who acted as commissioners in this delicate undertaking, only one, Titus, is known to us by name. He had just returned from Corinth; he knew all the critical points in the situation; and no doubt the Apostle was glad to have such a man at the head of the little party. He was thankful to God that on the occasion of that previous visit the Corinthians had completely won the heart of Titus, and that his loyal fellow-worker needed no compulsion to return. He was leaving[73] Paul of his own accord, full of earnest care for his Achaian friends. Along with him went a second--the brother whose praise in the Gospel was through all the Churches. It is useless to ask who the brother was. A very early opinion, alluded to by Origen, and represented apparently in the traditional subscription to this Epistle, identified him with Luke. Probably the ground for this identification was the idea that his "praise in the Gospel" referred to Luke's work as an evangelist. But this cannot be: first, because Luke's Gospel cannot have been written so early; and, secondly, because "the Gospel" at this date does not mean a written thing at all. This man's praise in the Gospel must mean the credit he had acquired by his services to the Christian faith; it might be by some bold confession, or by activity as an evangelist, or by notable hospitality to missionaries, or by such helpful ministries as the one he was now engaged in. The real point of interest for us in the expression is the glimpse it gives us of the unity of the Church, and the unimpeded circulation of one life through all its members. Its early divisions, theological and racial, have been sufficiently emphasised; it is well worth while to observe the unity of the spirit. It was this, eventually, which gave the Church its power in the decline of the Empire. It was the only institution which extended over the area of civilisation with a common spirit, common sympathies, and a common standard of praise. It was a compliment to the Corinthians to include in this embassy one whose good name was honoured wherever men met in the name of Jesus. This brother was at the same time a deputy in a special sense.
