There are many pastors today who, for fear of being branded 'legalists', give their congregation no ethical teaching. How far we have strayed from the apostles! 'Legalism' is the misguided attempt to earn our salvation by obedience to the law. 'Pharisaism' is a preoccupation with the externals and the minutiae of religious duty. To teach the standards of moral conduct which adorn the gospel is neither legalism not pharisaism but plain apostolic Christianity.
