<p>6:14 <i>Be not unequally yoked with unbelievers</i>- Paul now attempts to put his finger on why they were not acting to him as towards a parent, mimicking his openness (:13). It is because of associations with others. Paul's selfless relationship with Corinth was inspired by that of Moses with Israel. Thus Paul warns Corinth not to be unequally yoked with unbelievers (2 Cor. 6:14), or else he would come to them and not spare. He is quoting the LXX of Num. 25:3 concerning how Israel joined themselves to Baal-peor, resulting in Moses commanding the murder of all those guilty- just as Paul later did to Corinth. Israel were not to sow &quot;mingled seed&quot; in their fields, or make clothes of &quot;mingled&quot; materials (s.w. LXX Lev. 19:19). The materials would, as the Lord Himself mentioned, tear apart. The garment wouldn't last. And sowing different seeds together likewise would bring no fruit to perfection. But the LXX in these passages is quoted in one place only in the NT: &quot;Be not unequally yoked together with unbelievers&quot; (2 Cor. 6:14). If we are, <i>the relationship can't work</i>. So don't think that if we yoke with unbelievers, as Corinth were with the Judaizers, or if we marry out of the Faith, it will all work out OK somehow. Unless there is serious repentance (and even then, not always), <i>it won't work</i>. It will be a garment patched up with two different materials.</p><p><i>For what fellowship have righteousness and iniquity? Or what communion has light with darkness?</i>- &quot;Fellowship&quot; and &quot;communion&quot;, <i>kioinonia</i>, here carries the sense of 'What do they have in common?'. The Corinthians thought that they could be Christians, yoked to the Lord, whilst involved in idol worship and Judaism. But if Christ is the light- then all else is darkness. Paul has earlier used the metaphor of how in the new creation, light shines forth out of the darkness. Although Paul was very tolerant of the Corinthians, he knew that ultimately there can be no compromise. It's not that they 'ought not to fellowship' with darkness; his point is that light and darkness are mutually exclusive categories, there is nothing in common between them. This is all being said in support of the appeal earlier in this verse not to be unequally yoked with unbelievers. Equal yoking is in order to get a job done- ploughing for the Lord, doing His work. And we shall not be able to participate in His work if we are unequally yoked. Not because we are not 'allowed' to, but because in practice we will be pulling different ways.</p>
