But the Apostle does not stop short with claiming a bare equality with his rivals. "For though[84] I should boast somewhat more abundantly concerning our authority ... I shall not be put to shame"--_i.e._, "The facts I have invited you to look at will bear me out." The key to this passage is to be found in 1 Cor. xv. 15, where he boasts that, though the least of the apostles, and not worthy to be called an apostle, he had, through the grace of God given to him, laboured more abundantly than all the rest. If it came to comparison, then, of the attestation which Christ gave to their several labours, and so to their authority, by success in evangelising, it would not be Paul who would have to hide his head. But he does not choose to boast any more of his authority at this point. He has no desire to clothe himself in terrors; on the contrary, he wishes to avoid[85] the very appearance of scaring them out of their wits by his letters (for ἐκφοβεῖν compare Mark ix. 6; Heb. xii. 21). His authority has been given him, not for the pulling down, but for the building up, of the Church; it is not lordly (chap. i. 24), but ministerial; and he would wish, not only to show it in kindly service, but also in a kindly aspect. "Not for casting down," in ver. 8, is no contradiction of "mighty for casting down" in ver. 4: the object in the two cases is quite different. Many _things_ in man must be cast down--many high thoughts, much pride, much wilfulness, much presumption and sufficiency--but the casting down of these is the building up of souls.
