(_f_) Last, but not least, when St. Paul said, "Come out and be separate," he did not mean that Christians ought to withdraw from every Church in which there are unconverted members, or to refuse to worship in company with any who are not believers, or to keep away from the Lord's table if any ungodly people go up to it. This is a very common but a very grievous mistake. There is not a text in the New Testament to justify it, and it ought to be condemned as a pure invention of man. Our Lord Jesus Christ Himself deliberately allowed Judas Iscariot to be an apostle for three years, and gave him the Lord's Supper. He has taught us, in the parable of the wheat and tares, that converted and unconverted will be "together till the harvest," and cannot be divided. (Matt. xiii. 30.) In His Epistles to the Seven Churches, and in all St. Paul's Epistles, we often see faults and corruptions mentioned and reproved; but we are never told that they justify desertion of the assembly, or neglect of ordinances. In short, we must not look for a perfect Church, a perfect congregation, and a perfect company of communicants, until the marriage supper of the Lamb. If others are unworthy Churchmen, or unworthy partakers of the Lord's Supper, the sin is theirs and not ours: we are not their judges. But to separate ourselves from Church assemblies, and deprive ourselves of Christian ordinances, because others use them unworthily, is to take up a foolish, unreasonable, and unscriptural position. It is not the mind of Christ, and it certainly is not St. Paul's idea of separation from the world. I commend these six points to the calm consideration of all who wish to understand the subject of separation from the world. About each and all of them far more might be said than I have space to say in this paper. About each and all of them I have seen so many mistakes made, and so much misery and unhappiness caused by those mistakes, that I want to put Christians on their guard. I want them not to take up positions hastily, in the zeal of their first love, which they will afterwards be obliged to give up. I leave this part of my subject with two pieces of advice, which I offer especially to young Christians. I advise them, for one thing, if they really desire to come out from the world, to remember that the shortest path is not always the path of duty. To quarrel with all our unconverted relatives, to "cut" all our old friends, to withdraw entirely from mixed society, to live an exclusive life, to give up every act of courtesy and civility in order that we may devote ourselves to the direct work of Christ,--all this may seem very right, and may satisfy our consciences and save us trouble. But I venture a doubt whether it is not often a selfish, lazy, self-pleasing line of conduct, and whether the true cross and true line of duty may not be to deny ourselves, and adopt a very different course of action.
