I. How necessary the knowledge of ourselves is, its nature,
the danger of mistake, its leading parts, sect. 1, 2, 3. II. The causes of
Adam's fearful fall, sect. 4. III. The effects of the fall extending to Adam's
posterity, and all the creatures, sect. 5, to the end of the Chapter, where the
nature, propagation, and effect of original sin are considered.
2. Though there is plausibility in the sentiment which stimulates us to self-admiration, the only sound sentiment is that which inclines us to true humbleness of mind. Pretexts for pride. The miserable vanity of sinful man.
3. Different views taken by carnal wisdom and by conscience, which appeals to divine justice as its standard. The knowledge of ourselves, consisting of two parts, the former of which having already been discussed, the latter is here considered.
4. In considering this latter part, two points to be considered; 1. How it happened that Adam involved himself and the whole human race in this dreadful calamity. This the result not of sensual intemperance, but of infidelity (the source of other heinous sins), which led to revolt from God, from whom all true happiness must be derived. An enumeration of the other sins produced by the infidelity of the first man.
5. The second point to be considered is, the extent to which the contagious influence of the fall extends. It extends, 1. To all the creatures, though unoffending; and, 2. To the whole posterity of Adam. Hence hereditary corruption, or original sin, and the depravation of a nature which was previously pure and good. This depravation communicated to the whole posterity of Adam, but not in the way supposed by the Pelagians and Celestians.
6. Depravation communicated not merely by imitation, but by propagation. This proved, 1. From the contrast drawn between Adam and Christ. Confirmation from passages of Scripture; 2 From the general declaration that we are the children of wrath.
7. Objection, that if Adam's sin is propagated to his posterity, the soul must be derived by transmission. Answer. Another objection--viz. that children cannot derive corruption from pious parents. Answer.
8. Definition of original sin. Two parts in the definition. Exposition of the latter part. Original sin exposes us to the wrath of God. It also produces in us the works of the flesh. Other definitions considered.
9. Exposition of the former part of the definition--viz. that hereditary depravity extends to all the faculties of the soul.
10. From the exposition of both parts of the definition it follows that God is not the author of sin, the whole human race being corrupted by an inherent viciousness.
11. This, however, is not from nature, but is an adventitious quality. Accordingly, the dream of the Manichees as to two principles vanishes.
