Westminster Larger Catechism

The duties required in the ninth commandment are, the preserving and promoting of truth between man and man, and the good name of our neighbor, as well as our own: appearing and standing for the truth; and from the heart, sincerely, freely, clearly, and fully, speaking the truth, and only the truth, in matters of judgment and justice, and in all other things whatsoever; a charitable esteem of our neighbors; loving, desiring, and rejoicing in their good name; sorrowing for, and covering of their infirmities; freely acknowledging of their gifts and graces, defending their innocency; a ready receiving of good report, and unwillingness to admit of an evil report, concerning them; discouraging tale-bearers, flatterers, and slanderers; love and care of our own good name, and defending it when need requireth; keeping of lawful promises; study and practising of whatsoever things are true, honest, lovely, and of good report.

The sins forbidden in the ninth commandment are, all prejudicing the truth, and the good name of our neighbors, as well as our own, especially in public judicature; giving false evidence; suborning false witnesses; wittingly appearing and pleading for an evil cause; out-facing and overbearing the truth; passing unjust sentence; calling evil good, and good evil; rewarding the wicked according to the work of the righteous, and the righteous according to the work of the wicked; forgery; concealing the truth; undue silence in a just cause, and holding our peace when iniquity calleth for either a reproof from ourselves, or complaint to others; speaking the truth unseasonably, or maliciously to a wrong end, or perverting it to a wrong meaning, or in doubtful and equivocal expressions, to the prejudice of truth or justice; speaking untruth, lying, slandering, backbiting, detracting, tale-bearing, whispering, scoffing, reviling, rash, harsh, and partial censuring; misconstructing intentions, words, and actions; flattering, vain-glorious boasting, thinking or speaking too highly or too meanly of ourselves or others; denying the gifts and graces of God; aggravating smaller faults; hiding, excusing, or extenuating of sins, when called to a free confession; unnecessary discovering of infirmities; raising false rumours, receiving and countenancing evil reports, and stopping our ears against just defence; evil suspicion; envying or grieving at the deserved credit of any, endeavouring or desiring to impair it, rejoicing in their disgrace and infamy; scornful contempt; fond admiration; breach of lawful promises; neglecting such things as are of good report; and practicing or not avoiding ourselves, or not hindering what we can in others, such things as procure an ill name.

The tenth commandment is, Thou shalt not covet thy neighbor’s house, thou shalt not covet thy neighbor’s wife, nor his man-servant, nor his maid-servant, nor his ox, nor his ass, nor any thing that is thy neighbor’s.

The duties required in the tenth commandment are, such a full contentment with our own condition, and such a charitable frame of the whole soul toward our neighbor, as that all our inward motions and affections touching him, tend unto, and further all that good which is his.

The sins forbidden in the tenth commandment are, discontentment with our own estate; envying, and grieving at the good of our neighbor, together with all inordinate motions and affections to anything that is his.

No man is able, either of himself, or by any grace received in this life, perfectly to keep the commandments of God; but doth daily break them in thought, word, and deed.

All transgressions of the law of God are not equally heinous; but some sins in themselves, and by reason of several aggravations, are more heinous in the sight of God than others.

Sins receive their aggravations,

1. From the persons offending: if they be of riper age, greater experience or grace, eminent for profession, gifts, place, office, guides to others, and whose example is likely to be followed by others.
2. From the parties offended: if immediately against God, his attributes, and worship; against Christ, and his grace; the Holy Spirit, his witness, and workings; against superiors, men of eminency, and such as we stand especially related and engaged unto; against any of the saints, particularly weak brethren, the souls of them or any other, and the common good of all or many.
3. From the nature and quality of the offence: if it be against the express letter of the law, break many commandments, contain in it many sins: if not only conceived in the heart, but break forth in words and actions, scandalize others, and admit of no reparation: if against means, mercies, judgments, light of nature, conviction of conscience, public or private admonition, censures of the church, civil punishments; and our prayers, purposes, promises, vows, covenants, and engagements to God or men: if done deliberately, wilfully, presumptuously, impudently, boastingly, maliciously, frequently, obstinately, with delight, continuance, or relapsing after repentance.
4. From circumstances of time and place: if on the Lord’s day, or other times of divine worship; or immediately before or after these, or other helps to prevent or remedy such miscarriages: if in public, or in the presence of others, who are thereby likely to be provoked or defiled.

Every sin, even the least, being against the sovereignty, goodness, and holiness of God, and against his righteous law, deserveth his wrath and curse, both in this life, and that which is to come; and cannot be expiated but by the blood of Christ.
