Problems with the Westminster Confession of Faith
"to pass by" (III.7) God is not passive in any of His decrees.
"and power to fulfil it" (IV.2) Adam and Eve did not have the power to fulfill the Law of God.
"deceitfulness of their hearts" (V.5) A regenerate person's heart is not deceitful. A regenerate person is not totally depraved.
"to permit" (VI.1) God did not "permit" the fall; He ordained and caused the fall.
"The first covenant made with man was a covenant of works, wherein life was promised to Adam; and in him to his posterity, upon condition of perfect and personal obedience." (VII.2) There was no such monstrosity as a covenant of works. Nowhere did God promise Adam life upon condition of perfect obedience.
"common operations of the Spirit" (X.4) The unregenerate do not have any operations of the Spirit.
"the regenerate part" (XIII.3) A regenerate person does not have two parts, one regenerate and one unregenerate. He is wholly regenerate, a new creature, with a new heart, although he still has indwelling sin.
"growing up in many to the attainment of a full assurance" (XIV.3) All believers have full assurance.
"This infallible assurance doth not so belong to the essence of faith, but that a true believer may wait long, and conflict with many difficulties before he be a partaker of it" (XVIII.3) This is in direct contradiction to the definition of faith in Hebrews 11:1. There is no such monstrosity as a person who has faith but does not have assurance.
"True believers may have the assurance of their salvation divers ways shaken, diminished, and intermitted ... this assurance may, in due time, be revived" (XVIII.4). Same as above.
"and suffering such as fear Him to walk in darkness and to have no light" (XVIII.4) God does not allow His people to walk in darkness and have no light.
"God gave Adam a law, as a covenant of works, by which He bound him and all his posterity to personal, entire, exact, and perpetual obedience, promised life upon the fulfilling, and threatened death upon the breach of it, and endued him with power and ability to keep it." (XIX.1) Already went over this.
"and in greater boldness of access to the throne of grace, and in fuller communications of the free Spirit of God, than believers under the law did ordinarily partake of" (XX.1) Old Testament believers had just as much boldness to access the throne of grace and just as much communications of the Spirit of God as believers do now.
"beside religious oaths, vows, solemn fastings, and thanksgivings upon special occasions, which are, in their several times and seasons, to be used in an holy and religious manner." (XXI.5) Jesus said that we are not to swear at all but to let our yes be yes and our no be no. And the worship of God is to be regulated according to God's Word, meaning that there are no "special occasions."
"so, in His Word, by a positive, moral, and perpetual commandment binding all men in all ages, He hath particularly appointed one day in seven, for a Sabbath, to be kept holy unto Him: which, from the beginning of the world to the resurrection of Christ, was the last day of the week; and, from the resurrection of Christ, was changed into the first day of the week, which, in Scripture, is called the Lord's Day, and is to be continued to the end of the world, as the Christian Sabbath. This Sabbath is then kept holy unto the Lord ..." (XXI.7,8) There is no longer a Sabbath Day, since it was a shadow of coming things, but the body is of Christ. The Christian's Sabbath rest is in his resting from his works, not in a particular day.
"Of Lawful Oaths and Vows" (XXII). This entire section is unbiblical. There is no such thing as a lawful oath or vow.
"It is lawful for Christians to accept and execute the office of a magistrate ... so, for that end, they may lawfully, now under the new testament, wage war, upon just and necessary occasion" (XXIII.2). A Christian is not able to govern a secular society. And the only just wars are the ones that were commanded by God.
"it is the duty of civil magistrates to protect the Church of our common Lord, without giving the preference to any denomination of Christians above the rest" (XXIII.3) The government should have nothing to do with the Church, with what is or what is not a true church, including giving tax exempt status.
"It is lawful for all sorts of people to marry, who are able with judgment to give their consent." (XXIV.3) Everything that unregenerate people do is unlawful. The marriage of unregenerate people is not at all pleasing or legitimate in God's sight. It is wicked.
"In the case of adultery after marriage, it is lawful for the innocent party to sue out a divorce: and, after the divorce, to marry another, as if the offending party were dead." (XXIV.5) Remarriage after divorce is adultery. This section condones adultery.
"and seal of the covenant of grace, of his ingrafting into Christ, of regeneration, or remission of sins" (XXVIII.1) Baptism is not a seal of any of these things to the one baptized. It is not a seal at all. It is a sign to the church.
"by right use of this ordinance, the grace promised is not only offered, but really exhibited, and conferred, by the Holy Ghost, to such (whether of age or infants) as that grace belongeth unto" (XXVIII.6) Grace is not conferred in baptism.
"The Lord Jesus hath, in this ordinance, appointed His ministers to declare His word of institution to the people; to pray, and bless the elements of bread and wine, and thereby to set them apart from a common to an holy use; and to take and break the bread, to take the cup, and (they communicating also themselves) to give both to the communicants; but to none who are not then present in the congregation." (XXIX.3) This does not come from the Bible but from man-made tradition. There is liberty in how the Lord's Supper is administered. The elements are not "made holy" by "blessing" them.
