From this parable, and from the corresponding one of the wheat and the tares, we see what a mistake we make if we expect to find anywhere a perfect Church upon earth. To expect the Church to be a community of perfect saints is to expect more than its divine Founder ever expected, according to the words of His own parables. There was a Balaam among the prophets of God, and Achan in the camp of Israel, a Judas numbered with the twelve apostles, an Ananias and Sapphira connected with the first little flock in Jerusalem. In the Corinthian, Galatian, and Ephesian Churches, planted and superintended by St. Paul, there arose bad ministers and disreputable private Christians. No wonder, then, that in our church and charges there should be found reprehensible and undesirable material, and no preaching, however powerful and faithful, no discipline, however strict and prudent, no watchfulness, however careful and ready, can ever make it otherwise. Even to the end of the world the goats will mingle with the sheep, the tares grow up with the wheat, whilst the nets are being filled, the bad fish will be gathered with the good. Perfection is not to be found this side of heaven. The second error pointed out by this part of our subject is this, that we must not seek, by force or persecution, to get rid of what _we_ may call putrid or unprofitable fish. Church discipline is, indeed, enjoined in the Scripture in regard to doctrine and in regard to practice. When Paul writes to Titus: "Rebuke them sharply, that they may be sound in the faith," and advises the Corinthians concerning the man guilty of incest, "Put away from among yourselves that wicked person,"--when a person has become manifest as an outspoken disbeliever or as an open transgressor of God's Law, flagrant in his morals, then it becomes incumbent upon a congregation to admonish, to discipline, for the saving of his soul, that person. Church discipline is not intended to cast away, but to bring back to proper belief and proper conduct, to save a person's soul, to keep him in the net, by removing his error and inducing him to live a decent life. However, if such a one obstinately persists in his wickedness, then it commends itself to every one that he can no longer be admitted to fellowship.
