Synopsis of the Books of the Bible, by John Nelson Darby, [1857-62], at sacred-texts.com
After this the apostle answers the question respecting meats offered to idols, which gives occasion to a few words on the value of knowledge. Simply as knowledge, it is worth nothing. If we look at it as knowledge that we possess, it does but puffs us up; it is something in me, my knowledge. True christian knowledge unfolded something in God. By means of that which is revealed, God, better known, became greater to the soul. It was in Him the thing known, and not a knowledge in me by which I made myself greater. He who loves God is known of Him. As to the question itself, love decided it. Since such a question had arisen, it was evident that all consciences were not brought into full light by spiritual intelligence. Now undoubtedly the idol was nothing: there was but one God, the Father; and one Lord, Jesus Christ. But if he who was strong sat at meat in the idol's temple, another who had not full light would be encouraged to do the same, and his conscience would be unfaithful and defiled. Thus I lead into sin,and, as far as depends on me, I ruin a brother for whom Christ died. I sin against Christ Himself in so doing. Thus, if meat causes a brother to stumble, let me altogether abstain from it rather than be a snare to him. Here the apostle treats the question as arising among the brethren, so as that which regards the conscience of each, choosing to maintain in all its force that in fact an idol was nothing but a piece of wood or stone. It was important to set the question on this ground. The prophets had done so before. But this was not all that there was to say. There was the working of Satan and of wicked spirits to explain, and this he does further on.
We may remark in passing the expression, "To us there is but one God, the Father, and one Lord, Jesus Christ." The apostle does not here treat the abstract question of the Lord's divinity, but the connection of men with that which was above them in certain relationships. Pagans had many gods, and many lords, intermediate beings. Not so Christians. For them is the Father abiding in the absoluteness of the divinity, and Christ who, become man, has taken the place and the relationship of Lord towards us. The position, and not the nature, is the subject. It is the same thing in Co1 12:2-6, where the contrast is with the multitude of spirits whom the Pagans knew, and the number of gods and lords. Nevertheless every one was not, in fact, thus delivered from the influence of false gods on his imagination. They were still perhaps, in spite of himself, something to him. He had conscience of the idol, and if he ate that which had been offered to it, it was not to him simply that which God had given for food. The idea of the existence of a real and powerful being had a place in his heart, and thus his conscience was defiled. Now they were not better in God's sight for having eaten, and by eating they had put a stumbling block in their brother's way, and, so far as the act of those who had full light was concerned, had ruined him by defiling his conscience and estranging him from God in unfaithfulness. This was sinning against Christ, who had died for that precious soul. If God intervened to shield him from the result of this unfaithfulness, that in nowise diminished the sin of him who led the weak one to act against his conscience. In itself that which separates us from God ruins us in that which regards our responsibility. Thus he who has the love of Christ in his heart would rather never eat meat than do that which would make a brother unfaithful, and tend to ruin a soul which Christ has redeemed.
