Possible to every man is this personal union to Christ, but to be united thus in one Spirit to Christ and at the same time to be united to impurity is for ever impossible. To be one with Christ in spirit and at the same time to be one in body with what is spiritually defiled is impossible, and the very idea is monstrous. Devotedness to Christ is possible, but it is incompatible with any act which means that we become one in body with what is morally polluted. If the Christian is as truly a member of Christ's body as were the hands and eyes of the body He wore on earth, then the mind shrinks, as from blasphemy, from following out the thought of Paul. And if any frivolous Corinthian still objected that such acts went no deeper than the eating of food ceremonially unclean, that they belonged to the body that was to be destroyed, Paul says, It is not so; these acts are full of the deepest moral significance: they were intended by God to be _the expression of inward union_, and they have that significance whether you shut your eyes to it or not. And this is what Paul means when he goes on to say, "Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body." He does not mean that this is the only sin committed by the body, for of many other sins the body is the agent, as in murder, lying, blasphemy, robbery, and thieving. Neither does he mean that this is the only sin to which bodily appetite instigates, for gluttony and drunkenness equally take their rise in bodily appetite. But he means that this is the only sin in which the present connection of the body with Christ and its future destiny in Him are directly sinned against. This is the only sin, he means, which by its very nature alienates the body from Christ, its proper Partner. Other sins indirectly involve separation from Christ; this explicitly and directly transfers allegiance, and sunders our union with Him. By this sin a man detaches himself from Christ; he professes to be united to what is incompatible with Christ.
