Ver. 6. _Disappointed Hopes in Christian Work._--1. It is the duty of Christian ministers, not only to hold out the pure truth of the Gospel, but to defend it by convicting gainsayers and reproving solidly those who are carried away with contrary errors. 2. Ministers in all their reproofs are to use much wariness and circumspection, not omitting any circumstance which may justly extenuate the sin or furnish ground of hope of amendment. Hereby the bitter portion of a medicinal reproof is much sweetened, and the guilty patient allured to the more thorough receiving of it. 3. The most quick-sighted may be deceived and disappointed in their expectation of good things from some eminent professors, and so may readily fall short of their hope. 4. As the dangerous consequences which follow upon error ought to be presented unto people that they may fly from it, so there are some errors in doctrine which do no less separate from God than profanity of life doth, of which errors this is one--the maintaining of justification by works. 5. It is ordinary for seducers to usher in their errors by some excellent designations as of new lights, a more pure gospel way, and what not, as here they designate their error by the name of another gospel.--_Fergusson._ Ver. 7. _The Inviolable Unity of the Gospel._--1. There is but one Gospel, one in number and no more, and but one way to salvation, which is by faith. 2. The effect of error is to trouble the Church's peace; peace among themselves, the patrons of error being zealous of nothing so much as to gain many followers, to attain which they scruple not to make woeful rents and deplorable schisms; inward peace of conscience, while some are perplexed and anxious what to choose and refuse until they question all truth, and others to embrace error for truth and so ground their peace on an unsure foundation. 3. The doctrine which maintains that justification is partly by Christ and partly by the merit of good works is a perverting and total overturning of the Gospel, in so far as it contradicts the main scope of the Gospel, which is to exalt Christ as our complete Saviour, Mediator, and Ransom, and not in part only.--_Fergusson._ Ver. 8. _The Inviolability of Christianity._
