Definition
An adverb used in legal instruments — most notably oaths of office, official bonds, and surety bonds — to describe the standard of conduct required of a person serving in a position of trust. When incorporated into such instruments, "faithfully" imposes a demanding performance standard that encompasses not merely honesty and good faith, but the full, diligent, and competent discharge of all duties attached to the role. It covers errors of omission (nonfeasance) and active wrongdoing (malfeasance) alike, and does not excuse a failure of performance attributable to mere incompetence or inattention — even absent any fraudulent intent.
The term appears most prominently in constitutional and statutory oaths of office ("faithfully execute," "faithfully discharge") and in the conditions of official bonds, where its breach can trigger liability for the officer and the surety.
Common Language
Modern common usage (Wiktionary): "In a faithful manner." Also used as a conventional letter-closing formula when the salutation names the intended recipient by title or honorific.
Historical common usage (Webster's 1913): With good faith; honestly; sincerely; with strict adherence to duty or obligation; with strict observance of promises, vows, or duties.
The gap between common and legal usage is one of degree and scope, not kind. Ordinary usage treats "faithfully" as roughly synonymous with "honestly" or "sincerely." Legal usage, particularly in official bonds and oaths, loads the term with a far heavier technical burden: honest intent is only a floor. Competence, diligence, punctuality of performance, and freedom from both malfeasance and nonfeasance are all swept in. A well-meaning but incompetent or inattentive officer may breach a "faithfully" standard even though no common speaker would say they acted unfaithfully.
Core Elements
When "faithfully" appears as a condition in an official bond or oath, courts have read it to require:
1. Honesty — absence of fraud, corruption, or bad faith.
2. Competence — the officer must bring the skill the position requires.
3. Diligence — active attention to the duties of the office; passivity is not a defense.
4. Completeness of performance — all duties, not merely those the officer finds convenient or prominent.
5. Freedom from malfeasance — no wrongful acts in the execution of duties.
6. Freedom from nonfeasance — no omissions of duties that the office legally demands.
Mere mistakes, unaccompanied by neglect or want of diligence, are not necessarily a breach of a "faithfully" condition. The standard is not perfection but the full, attentive, and honest exercise of official responsibility.
Why It Matters in Research
Researchers will encounter "faithfully" in at least three distinct legal contexts, each with different research implications:
Constitutional oaths and the "faithfully execute" clause. The U.S. Constitution uses "faithfully" twice in close proximity — in the Oath or Affirmation Clause (Article II, Section 1) and the Take Care Clause (Article II, Section 3). The constitutional dimensions of "faithfully execute" have generated significant scholarship and periodic litigation. Researchers moving from a surety-bond context into constitutional executive power questions should treat these as related but distinct bodies of doctrine.
Official bonds and surety liability. The Black's definition is squarely aimed at this context. When a public officer's bond is conditioned on "faithful" performance, the surety's liability turns on what "faithfully" demands. Historical cases from the nineteenth century are numerous and often inconsistent on whether mere negligence — short of willful misconduct — triggers the condition. Researchers should check the jurisdiction carefully; the threshold for breach varies.
Private employment and agency. "Faithfully" also appears in private employment bonds and agency agreements. The standard applied in private contexts may be somewhat less demanding than in public office contexts, though the same core elements of honesty and diligence typically apply.
A research trap: older sources, including many nineteenth-century treatises, discuss "faithfully" almost entirely in the public-officer-bond context. Applying that authority mechanically to a modern employment or agency question may produce distorted results.
Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) is the principal historical source for the legal meaning of this term as a term of art. Its definition is notable for expressly rejecting a reading limited to honesty: the entry states that "faithfully" in official bonds "imports not only honesty, but also a punctilious discharge of all the duties of the office, requiring competence, diligence, and attention, without any malfeasance or nonfeasance, aside from mere mistakes." The phrase "punctilious discharge" is worth attention — it signals that courts were reading "faithfully" to impose an active, exacting standard, not a passive good-faith one.
The supporting cases cited in Black's (State v. Chadwick, Hoboken v. Evans, Harris v. Hanson, American Bank v. Adams) are nineteenth-century American cases applying the standard in official bond contexts. They reflect a period when surety bonds for public officers were common and frequently litigated, and when courts were working out the precise contours of what the bond condition required.
What historical dictionary sources do not address: the constitutional dimensions of "faithfully" in the Take Care Clause and the Oath Clause. Those questions were not the focus of bond-law treatises and nineteenth-century dictionaries, and researchers should not expect historical legal dictionaries to illuminate them.
Jurisdictional Note
The precise threshold at which conduct breaches a "faithfully" condition in an official bond varies by jurisdiction and by whether the bond is governed by statute or common law. Some states have codified the duties of particular officers in ways that define what "faithful" performance requires for that office specifically, effectively supplementing or displacing the general common-law standard.
