As to what concerns the body, to which the soul was united, as giving occasion to these corrupt habits being contracted thereby, some have compared this to sweet oil’s being infected by a musty vessel, into which it is put; so the soul, created good, and put into a corrupt body, receives contagion from thence: and this conjunction of the pure soul with a corrupt body, is a just punishment of Adam’s sin. Thus a very learned and excellent divine accounts for this matter;[76] though this similitude does not indeed illustrate this matter in every circumstance, inasmuch as that tincture, which is received from a vessel in a physical way, cannot well agree with the corruption of the soul, which is of a moral nature; but yet I would make this use of it, as to observe what daily experience suggests, namely, that the constitution, or temperament of the body, has a very great influence on the soul, and is an occasion of various inclinations to sin, in which it acts, in an objective way. Therefore when we suppose a soul united to a body, that, according to the frame and constitution of its nature has a tendency to incline it to sin, and this soul is deprived of those supernatural habits, which would have fenced it against this contagion; what can ensue from hence, but that corruption of nature, whereby men are inclined to what is evil? which inclination increases daily, till men arrive to the most rooted habits and dispositions to all that is bad, and are, with more difficulty, reclaimed from it. This leads us to consider, IV. The conveyance of original sin, from our first parents to their posterity, by natural generation, or how we are said to be born in sin. It is not the sin of our immediate parents that is imputed to us, for they stand in no other relation, but as natural, and not federal heads of their posterity; therefore the meaning of that answer, in which this doctrine is contained, is only this, that original sin is conveyed to us, by our immediate parents, with our being; so that, as we are born men, we are born sinners. Now, that we may consider this in consistency with what has been before laid down nothing can be inferred, from hence, but that the guilt of Adam’s first sin is conveyed to us with our being, and that habitual inclination that we have, which we call a propensity of nature to sin, is the consequence hereof; so that what our Saviour says, is a great truth, _That which is born of the flesh, is flesh_, John iii. 6. or every one that is born of sinful parents, will, as soon as he is capable thereof, be prone to sin. And this leads us to consider,
