6. And unskilful teachers do cause the griefs and perplexities of very many. Some cannot open to them clearly the tenor of the covenant of grace; some are themselves unacquainted with any spiritual, heavenly consolations; and many have no experience of any inward holiness, and renewal by the Holy Ghost, and know not what sincerity is, nor wherein a saint doth differ from an ungodly sinner. As wicked deceivers make good and bad to differ but a little, if not the best to be taken for the worst; so some unskilful men do place sincerity in such things as are not so much as duty; as the Papists, in their manifold inventions and superstitions; and many sects, in their unsound opinions.
And some unskilfully and unsoundly describe the state of grace, and tell you how far a hypocrite may go, so as unjustly discourageth and confoundeth the weaker sort of Christians, and cannot amend the mis-expression of their books or teachers. And too many teachers lay men’s comforts, if not salvation, on controversies which are past their reach, and pronounce heresy and damnation against that which they themselves understand not. Even the Christian world, these one thousand three hundred, or one thousand two hundred years, is divided into parties, by the teachers’ unskilful quarrels about words, which they took in several senses. Is it any wonder if the hearers of such are distracted?
