Heidelberg Catechism, Lord’s day 31

31. Lord’s Day

Q. 83. What are the keys of the kingdom of heaven?
A. The preaching of the holy gospel, and christian discipline, or excommunication out of the christian church; by these two, the kingdom of heaven is opened to believers, and shut against unbelievers.

Q. 84. How is the kingdom of heaven opened and shut by the preaching of the holy gospel?
A. Thus: when according to the command of Christ, it is declared and publicly testified to all and every believer, that, whenever they receive the promise of the gospel by a true faith, all their sins are really forgiven them of God, for the sake of Christ’s merits; and on the contrary, when it is declared and testified to all unbelievers, and such as do not sincerely repent, that they stand exposed to the wrath of God, and eternal condemnation, so long as they are unconverted: [a] according to which testimony of the gospel, God will judge them, both in this, and in the life to come.

Q. 85. How is the kingdom of heaven shut and opened by christian discipline?
A. Thus: when according to the command of Christ, those, who under the name of christians, maintain doctrines, or practices inconsistent therewith, and will not, after having been often brotherly admonished, renounce their errors and wicked course of life, are complained of to the church, or to those, who are thereunto appointed by the church; and if they despise their admonition, are by them forbidden the use of the sacraments; whereby they are excluded from the christian church, and by God himself from the kingdom of Christ; and when they promise and show real amendment, are again received as members of Christ and his church. [a]

Westminster Confession, week 31

Chapter 19: Of the Law of God

3: Besides this law, commonly called moral, God was pleased to give to the people of Israel, as a church under age, ceremonial laws, containing several typical ordinances, partly of worship, prefiguring Christ, His graces, actions, sufferings, and benefits;^[368] and partly, holding forth divers instructions of moral duties.^[369] All which ceremonial laws are now abrogated, under the New Testament.^[370]

4: To them also, as a body politic, He gave sundry judicial laws, which expired together with the State of that people; not obliging under any now, further than the general equity thereof may require.^[371]

5: The moral law does forever bind all, as well justified persons as others, to the obedience thereof;^[372] and that, not only in regard of the matter contained in it, but also in respect of the authority of God the Creator, who gave it.^[373] Neither does Christ, in the Gospel, any way dissolve, but much strengthen this obligation.^[374]

The Third and Fourth Heads of Doctrine: Human Corruption, Conversion to God, and the Way It Occurs

Article 15: Responses to God’s Grace

God does not owe this grace to anyone. For what could God owe to one who has nothing to give that can be paid back? Indeed, what could God owe to one who has nothing of his own to give but sin and falsehood? Therefore the person who receives this grace owes and gives eternal thanks to God alone; the person who does not receive it either does not care at all about these spiritual things and is satisfied with himself in his condition, or else in self-assurance foolishly boasts about having something which he lacks. Furthermore, following the example of the apostles, we are to think and to speak in the most favorable way about those who outwardly profess their faith and better their lives, for the inner chambers of the heart are unknown to us. But for others who have not yet been called, we are to pray to the God who calls things that do not exist as though they did. In no way, however, are we to pride ourselves as better than they, as though we had distinguished ourselves from them.

Article 16: Regeneration’s Effect

However, just as by the fall man did not cease to be man, endowed with intellect and will, and just as sin, which has spread through the whole human race, did not abolish the nature of the human race but distorted and spiritually killed it, so also this divine grace of regeneration does not act in people as if they were blocks and stones; nor does it abolish the will and its properties or coerce a reluctant will by force, but spiritually revives, heals, reforms, and — in a manner at once pleasing and powerful — bends it back. As a result, a ready and sincere obedience of the Spirit now begins to prevail where before the rebellion and resistance of the flesh were completely dominant. It is in this that the true and spiritual restoration and freedom of our will consists. Thus, if the marvelous Maker of every good thing were not dealing with us, man would have no hope of getting up from his fall by his free choice, by which he plunged himself into ruin when still standing upright.

Q. 125. Why are superiors styled father and mother?
A. Superiors are styled father and mother, both to teach them in all duties toward their inferiors, like natural parents, to express love and tenderness to them, according to their several relations;^[655] and to work inferiors to a greater willingness and cheerfulness in performing their duties to their superiors, as to their parents.^[656]

Q. 126. What is the general scope of the fifth commandment?
A. The general scope of the fifth commandment is, the performance of those duties which we mutually owe in our several relations, as inferiors, superiors, or equals.^[657]

Belgic Confession, week 4

Article 8: The Trinity

In keeping with this truth and Word of God we believe in one God, who is one single essence, in whom there are three persons, really, truly, and eternally distinct according to their incommunicable properties– namely, Father, Son, and Holy Spirit. The Father is the cause, origin, and source of all things, visible as well as invisible. The Son is the Word, the Wisdom, and the image of the Father. The Holy Spirit is the eternal power and might, proceeding from the Father and the Son. Nevertheless, this distinction does not divide God into three, since Scripture teaches us that the Father, the Son, and the Holy Spirit each has his own subsistence distinguished by characteristics– yet in such a way that these three persons are only one God. It is evident then that the Father is not the Son and that the Son is not the Father, and that likewise the Holy Spirit is neither the Father nor the Son. Nevertheless, these persons, thus distinct, are neither divided nor fused or mixed together. For the Father did not take on flesh, nor did the Spirit, but only the Son. The Father was never without his Son, nor without his Holy Spirit, since all these are equal from eternity, in one and the same essence. There is neither a first nor a last, for all three are one in truth and power, in goodness and mercy.

A. The first commandment forbiddeth the denying,^[121] or not worshiping and glorifying, the true God as God,^[122] and our God;^[123] and the giving of that worship and glory to any other, which is due to him alone.^[124]

Q. 48. What are we specially taught by these words before me in the first commandment?
A. These words before me in the first commandment teach us, that God, who seeth all things, taketh notice of, and is much displeased with, the sin of having any other God.^[125]

Heidelberg Catechism, Lord’s day 30

30. Lord’s Day

Q. 80. What difference is there between the Lord’s supper and the popish mass?
A. The Lord’s supper testifies to us, that we have a full pardon of all sin by the only sacrifice of Jesus Christ, which he himself has once accomplished on the cross; [a] and, that we by the Holy Ghost are ingrafted into Christ, [b] who, according to his human nature is now not on earth, but in heaven, at the right hand of God his Father, [c] and will there be worshipped by us. [d] But the mass teaches, that the living and dead have not the pardon of sins through the sufferings of Christ, unless Christ is also daily offered for them by the priests; and further, that Christ is bodily under the form of bread and wine, and therefore is to be worshipped in them; so that the mass, at bottom, is nothing else than a denial of the one sacrifice and sufferings of Jesus Christ, and an accursed idolatry. [e]

Q. 81. For whom is the Lord’s supper instituted?
A. For those who are truly sorrowful for their sins, and yet trust that these are forgiven them for the sake of Christ; and that their remaining infirmities are covered by his passion and death; and who also earnestly desire to have their faith more and more strengthened, and their lives more holy; but hypocrites, and such as turn not to God with sincere hearts, eat and drink judgment to themselves. [a]

Q. 82. Are they also to be admitted to this supper, who, by confession and life, declare themselves unbelieving and ungodly?
A. No; for by this, the covenant of God would be profaned, and his wrath kindled against the whole congregation; [a] therefore it is the duty of the christian church, according to the appointment of Christ and his apostles, to exclude such persons, by the keys of the kingdom of heaven, till they show amendment of life.

Westminster Confession, week 30

Chapter 19: Of the Law of God

1: God gave to 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.^[365]

2: This law, after his fall, continued to be a perfect rule of righteousness; and, as such, was delivered by God upon Mount Sinai, in ten commandments, and written in two tables:^[366] the first four commandments containing our duty towards God; and the other six, our duty to man.^[367]

The Third and Fourth Heads of Doctrine: Human Corruption, Conversion to God, and the Way It Occurs

Article 13: The Incomprehensible Way of Regeneration

In this life believers cannot fully understand the way this work occurs; meanwhile, they rest content with knowing and experiencing that by this grace of God they do believe with the heart and love their Savior.

Article 14: The Way God Gives Faith

In this way, therefore, faith is a gift of God, not in the sense that it is offered by God for man to choose, but that it is in actual fact bestowed on man, breathed and infused into him. Nor is it a gift in the sense that God bestows only the potential to believe, but then awaits assent — the act of believing — from man’s choice; rather, it is a gift in the sense that he who works both willing and acting and, indeed, works all things in all people produces in man both the will to believe and the belief itself.
