Continuing what I began below, I am looking at the Ninth Commandment.

Question 143: Which is the ninth commandment?

Answer: The ninth commandment is, Thou shalt not bear false witness against thy neighbor.

Question 144: What are the duties required in the ninth commandment?

Answer: 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 a good report, and unwillingness to admit of an evil report, concerning them; discouraging talebearers, flatterers, and slanderers; love and care of our own good name, and defending it when need requires; keeping of lawful promises; studying and practicing of: Whatsoever things are true, honest, lovely, and of good report.

Question 145: What are the sins forbidden in the ninth commandment?

Answer: 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, outfacing 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 calls 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, vainglorious 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 rumors, receiving and countenancing evil reports, and stopping our ears against just defense; evil suspicion; envying or grieving at the deserved credit of any, endeavoring 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 area of my life in which I sin the most with respect to this commandment is the area of political discourse. I have a tendency (I'm being kind to myself in calling it that!) to be very uncharitable to my ideological opponents. I do not, to be brutally honest, have a "charitable esteem of [them]."

I have to confess that in all honesty I think I do better than those same ideological opponents I've mentioned. But that's no good: the commandment informs me that my neighbors' own actions respecting the commandment are irrelevant to my case. I am guilty. My neighbors' guilt won't help my cause.
