IN ITS OWN WORDS
AUTHORITY OF SCRIPTUREThe supream judge by which all controversies of Religion are to be determined, and all Decrees of Councels, opinions of antient Writers, Doctrines of men, and private Spirits, are to be examined, and in whose sentence we are to rest, can be no other but the Holy Scripture delivered by the Spirit.
2LBC 1.10 (1677/1689 printing, original spelling)
CANON OF THE OLD TESTAMENTThe Books commonly called Apocrypha not being of Divine inspiration, are no part of the Canon (or rule) of the Scripture, and therefore are of no authority to the Church of God, nor to be any otherwise approved or made use of, then other humane writings.
2LBC 1.3 (1677/1689 printing, original spelling)
NATURAL / GENERAL REVELATIONAlthough the light of Nature, and the works of Creation and Providence do so far manifest the goodness, wisdom and power of God, as to leave men unexcusable; yet are they not sufficient to give that knowledge of God and His will, which is necessary unto Salvation.
2LBC 1.1 (1677/1689 printing, original spelling)
THE TRINITYIn this divine and infinite Being there are three subsistences, the Father the Word (or Son) and Holy Spirit, of one substance, power, and Eternity, each having the whole Divine Essence, yet the Essence undivided.
2LBC 2.3 (1677/1689 printing, original spelling)
THE PERSON OF CHRISTSo that two whole, perfect, and distinct natures, were inseparably joined together in one Person: without conversion, composition, or confusion: which Person is very God, and very Man; yet one Christ, the only Mediator between God and Man.
2LBC 8.2 (1677/1689 printing, original spelling)
ORIGINAL SIN & THE HUMAN WILLMan by his fall into a state of sin hath wholly lost all ability of Will, to any spiritual good accompanying salvation; so as a natural man, being altogether averse from that good, and dead in Sin, is not able, by his own strength, to convert himself; or to prepare himself thereunto.
2LBC 9.3 (1677/1689 printing, original spelling)
ELECTION & PREDESTINATIONThose of mankind that are predestinated to life, God before the foundation of the world was laid, according to his eternal and immutable purpose, and the secret Councel and good pleasure of his will, hath chosen in Christ unto everlasting glory, out of his meer free grace and love; without any other thing in the creature as a condition or cause moving him thereunto.
2LBC 3.5 (1677/1689 printing, original spelling)
THE NATURE OF SAVING FAITHBy this Faith, a Christian believeth to be true, whatsoever is revealed in the Word, for the Authority of God himself ... and so is enabled to cast his Soul upon the truth thus beleived ... But the principal acts of Saving Faith, have immediate relation to Christ, accepting, receiving, and resting upon him alone, for Justification, Sanctification, and Eternal Life.
2LBC 14.2 (1677/1689 printing, original spelling)
JUSTIFICATIONnot by infusing Righteousness into them, but by pardoning their sins, and by accounting, and accepting their Persons as Righteous ... but by imputing Christs active obedience unto the whole Law, and passive obedience in his death, for their whole and sole Righteousness.
2LBC 11.1 (1677/1689 printing, original spelling)
EXTENT OF THE ATONEMENTThe Lord Jesus by his perfect obedience and sacrifice of himself, which he through the Eternal Spirit once offered up unto God, hath fully satisfied the Justice of God, procured reconciliation, and purchased an Everlasting inheritance in the Kingdom of Heaven, for all those whom the Father hath given unto him.
2LBC 8.5 (1677/1689 printing, original spelling)
PERSEVERANCE & ETERNAL SECURITYThose whom God hath accepted in the beloved, effectually called and Sanctified by his Spirit, and given the precious faith of his Elect unto, can neither totally nor finally fall from the state of grace; but shall certainly persevere therein to the end and be eternally saved.
2LBC 17.1 (1677/1689 printing, original spelling)
INDWELLING OF THE HOLY SPIRITThis Effectual Call is of God's free, and special grace alone, not from any thing at all foreseen in man, nor from any power, or agency in the Creature, coworking with his special Grace, the Creature being wholly passive therein, being dead in sins and trespasses, until being quickned & renewed by the holy Spirit, he is thereby enabled to answer this call.
2LBC 10.2 (1677/1689 printing, original spelling)
BAPTISMThose who do actually professe repentance towards God, faith in, and obedience, to our Lord Jesus, are the only proper subjects of this ordinance.
2LBC 29.2 (1677/1689 printing, original spelling)
THE LORD'S SUPPERWorthy receivers, outwardly partaking of the visible Elements in this Ordinance, do then also inwardly by faith, really and indeed, yet not carnally, and corporally, but spiritually receive, and feed upon Christ crucified & all the benefits of his death: the Body and Blood of Christ, being then not corporally, or carnally, but spiritually present to the faith of Believers.

2LBC 32.1 (1677/1689 printing, original spelling)
WHAT PEOPLE GET WRONG
AUTHORITY OF SCRIPTURETwo small departures from Westminster are easy to miss and both point the same way. WCF 1.10 makes the supreme judge 'the Holy Spirit speaking in the Scripture'; 2LBC 1.10 makes it the Scripture itself, 'delivered by the Spirit.' And where WCF 1.6 admits what may 'by good and necessary consequence be deduced from Scripture,' 2LBC 1.6 says only what is 'expressely set down or necessarily contained' in it — the same phrase Baptists used to resist inferring infant baptism from the covenant.
NATURAL / GENERAL REVELATIONChapter 20 is regularly quoted as though the confession denied natural revelation outright. It does not. It denies one specific thing — that nature reveals Christ or saving grace: 'neither do the Works of Creation, or Providence, with the light of Nature, make discovery of Christ, or of Grace by him; so much as in a general, or obscure way; much less that men destitute of the Revelation of him by the Promise, or Gospel; should be enabled thereby, to attain saving Faith, or Repentance' (2LBC 20.2). The inexcusable-but-insufficient revelation of 1.1 stands untouched.
ELECTION & PREDESTINATIONThe 1689 is softer than Westminster on the reprobate side, and readers who assume it simply reproduces WCF 3 will misquote it. WCF 3.3 has the non-elect 'foreordained to everlasting death'; 2LBC 3.3 has them 'left to act in their sin to their just condemnation'. WCF 3.7, the paragraph on passing by and ordaining to dishonour and wrath, has no counterpart in the 1689 at all. Election itself is unchanged; reprobation is stated as preterition only.
JUSTIFICATIONThis chapter is often described as verbatim Westminster. It is not. WCF 11.1 imputes "the obedience and satisfaction of Christ"; 2LBC 11.1 spells that out as "Christs active obedience unto the whole Law, and passive obedience in his death, for their whole and sole Righteousness" — taking a side in a dispute Westminster's broader wording had left open. The 1689 is commonly said to be following the Savoy Declaration here; that particular attribution was not verified against the Savoy text this run.
EXTENT OF THE ATONEMENTChapter 20, 'Of the Gospel, and of the extent of the Grace thereof', gets cited on this question and does not belong to it. Its subject is why the gospel has been preached to some nations and ages and not others — an extent of proclamation, not an extent of purchase. The definite-atonement texts are 3.6, 8.5 and 8.8.
PERSEVERANCE & ETERNAL SECURITYNot verbatim Westminster, though it is usually cited that way. 17.1 adds 'and given the precious faith of his Elect unto' plus a long assurance clause; 17.2 adds union with Christ and the oath of God to Westminster's list of grounds; and 17.3 ends with a promise of renewed repentance that WCF 17.3 does not contain.
INDWELLING OF THE HOLY SPIRITThe 1689 sharpens Westminster here rather than following it. WCF 10.2 says the sinner is 'altogether passive'; 2LBC 10.2 adds that the call comes 'nor from any power, or agency in the Creature, coworking with his special Grace' and that the change requires 'no less power, then that which raised up Christ from the dead' — an explicit exclusion of any cooperating agency. A second sharpening runs the other way. Chapter 20.4 is taken over from the Savoy Declaration of 1658, which required "an effectual, irresistible work of the Holy Ghost"; the Baptists kept the sentence and changed the adjective to "insuperable" — a work that cannot be overcome rather than one that cannot be resisted.
BAPTISMThe two confessions contradict each other clause for clause, and both sides are worth having in front of you. WCF 28.4: 'Not only those that do actually profess faith in and obedience unto Christ, but also the infants of one or both believing parents are to be baptized.' WCF 28.3: 'Dipping of the person into the water is not necessary; but baptism is rightly administered by pouring or sprinkling water upon the person.' Against that, 2LBC 29.4: 'Immersion, or dipping of the person in water, is necessary to the due administration of this ordinance.' 2LBC 29.1 also drops Westminster's description of baptism as admission into the visible church and as a seal of the covenant of grace.
THE LORD'S SUPPEROne small omission distinguishes it from Westminster. WCF 29.7 denies that the body and blood are 'corporally or carnally in, with, or under the bread and wine' — a targeted rejection of the Lutheran formula. The 1689 drops the 'in, with, or under' clause and simply denies corporal presence.
CONTINUATION OF SPIRITUAL GIFTS2LBC 1.1 is routinely offered as the confession's cessationism and it will not carry that weight: the sentence is the conclusion of an argument about why Scripture had to be committed to writing, and it is Westminster's sentence verbatim, so a reader who takes it as a ruling on charismatic practice is committed to reading WCF 1.1 the same way. Chapter 22.3 is the only place the confession uses the word tongue at all, requiring public prayer to be made "in a known tongue" (proof text 1 Corinthians 14:16-17) — a rule about intelligibility in the assembly, not a ruling on whether the gift continues. Chapters 26.9 and 26.11 assume the Spirit still gifts and fits men for office and for preaching.
THE MILLENNIUM & CHRIST'S RETURNWestminster is silent here too, so this is not a Baptist departure. The 1689 does not so much decline the question as never raise it.
