I. 1. We _establish the law_, first, By our doctrine: by endeavouring to preach it in its whole extent, to explain and inforce every part of it, in the same manner as our great Teacher did, while upon earth. We establish it, by following St. _Peter_’s advice, _If any man speak let him speak as the oracles of God_; as the holy men of old moved by the Holy Ghost, spoke and wrote for our instruction, and as the apostles of our blessed Lord, by the direction of the same spirit. We establish it whenever we speak in his name, by keeping back nothing from them that hear; by declaring to them, without any limitation or reserve, the whole counsel of God. And in order the more effectually to establish it, we use herein great plainness of speech. _We are not as many that corrupt the word of God_, καπηλεύουσι· (as artful men their bad wines) we do not cauponize, mix, adulterate or soften it, to make it suit the taste of the hearers. _But as of sincerity, but as of God in the sight of God, speak we in Christ_: as having no other aim, than _by manifestation of the truth_, to _commend ourselves to every man’s conscience in the sight of God_. 2. We then by our doctrine establish the law, when we thus openly declare it to all men: and that, in the fulness wherein it is delivered by our blessed Lord and his apostles: when we publish it in the height and depth and length and breadth thereof. We then establish the law, when we declare every part of it, every commandment contained therein, not only in its full literal sense, but likewise in its spiritual meaning: not only with regard to the outward actions, which it either forbids or enjoins: but also with respect to the inward principle, to the thoughts, desires and intents of the heart.
