In the next place, it is not of uncleanness; that is, it is not prompted by any impure motive. The force of the word here must be determined by the context; and we see that the impure motives specially laid to the charge of Paul were avarice and ambition; or, to use the words of the Apostle himself, covetousness, and the seeking of honour from men. The first of these is so manifestly inconsistent with any degree of spirituality that Paul writes instinctively "_a cloke_ of covetousness"; he did not make his apostolic labour a veil, under cover of which he could gratify his love of gain. It is impossible to exaggerate the subtle and clinging character of this vice. It owes its strength to the fact that it can be so easily cloked. We seek money, so we tell ourselves, not because we are covetous, but because it is a power for all good purposes. Piety, charity, humanity, refinement, art, science--it can minister to them all; but when we obtain it, it is too easily hoarded, or spent in indulgence, display, and conformity to the world. The pursuit of wealth, except in an utterly materialised society, is always cloked by some ideal end to which it is to minister; but how few there are in whose hands wealth is merely an instrument for the furtherance of such ends. In many men the desire for it is naked selfishness, an idolatry as undisguised as that of Israel at Sinai. Yet all men feel how bad and mean it is to have the heart set on money. All men see how base and incongruous it is to make godliness a source of gain. All men see the peculiar ugliness of a character which associates piety and avarice--of a Balaam, for instance, a Gehazi, or an Ananias. It is not ministers of the gospel only, but all to whom the credit of the gospel is entrusted, who have to be on their guard here. Our enemies are entitled to question our sincerity when we can be shown to be lovers of money. At Thessalonica, as elsewhere, Paul had been at pains to make such calumny impossible. Although entitled to claim support from the Church in accordance with the law of Christ that they who preach the gospel should live by the gospel, he had wrought night and day with his own hands that he might not burden any of them. As a precaution, this self-denial was vain; there can be no security against malice; but it gave him a triumphant vindication when the charge of covetousness was actually made.
