11. But because no man can believe _Jesus to be the Christ_, who, when he knows that by Christ is understood that same king, who was promised from God by Moses and the prophets for to be the king and Saviour of the world, doth not also believe Moses and the prophets; neither can he believe these, who believes not that God is, and that _he governs the world_; it is necessary, that the faith of God and of the Old Testament be contained in this faith of the New. Seeing therefore that atheism, and the denial of the Divine Providence, were the only treason against the Divine Majesty in the kingdom of God by nature; but idolatry also in the kingdom of God by the old covenant; now in this kingdom, wherein God rules by way of a new covenant, apostacy is also added, or the renunciation of this article once received, that Jesus is the Christ. Truly other doctrines, provided they have their determination from a lawful Church, are not to be contradicted; for that is the sin of disobedience. But it hath been fully declared before, that they are not needful to be believed with an _inward faith_. [Sidenote: How faith and obedience do concur to salvation.] 12. _Faith_ and _obedience_ have divers parts in accomplishing the salvation of a Christian; for this contributes the _power_ or _capacity_, that the _act_; and either is said to justify in its kind. For Christ forgives not the sins of all men, but of the _penitent_ or the _obedient_, that is to say, the _just_. I say not the _guiltless_, but the _just_; for _justice_ is a will of obeying the laws, and may be consistent with a sinner; and with Christ, the will to obey is obedience. For not every man, but _the just shall live by faith_. _Obedience_ therefore _justifies_, because it _maketh just_; in the same manner as temperance maketh temperate, prudence prudent, chastity chaste; namely, essentially; and puts a man in such a state, as makes him capable of pardon. Again, Christ hath not promised forgiveness of sins to all just men; but only _those of them who believe him to be the Christ_. _Faith_ therefore _justifies_ in such a sense as a judge may be said to _justify_, who _absolves_, namely, by the _sentence_ which _actually_ saves a man; and in this acception of justification (for it is an equivocal term) _faith alone_ justifies; but in the other, _obedience only_. But neither obedience alone, nor faith alone, do _save_ us; but both together. [Sidenote: In a Christian city there is no contrariety between the command of God, and of the city.]
