"Now they that think they may come to justification by performance of the law, by their own deeds and merits, or by any other mean than is above rehearsed, they go from Christ, they renounce his grace: Evacuati estis a Christo, saith St. Paul, Gal. v., quicunque, in lege, judificamini, a gratia excidistis. They be not partakers of the justice, that he hath procured, or the merciful benefits that be given by him. For St. Paul saith a general rule for all them that will seek such by-paths to obtain justification; those, saith he, which will not knowledge the justness or righteousness which cometh by God, but go about to advance their own righteousness, shall never come to that righteousness which we have by God (Rom. 10:1-4); which is the righteousness of Christ: by whom only all the saints in heaven, and all other that have been saved, have been reputed righteous, and justified. So that to Christ our only Saviour and Redeemer, on whose righteousness both their and our justification doth depend, is to be transcribed all the glory thereof."
