Other meanings of Imprimatur
Censorship
An imprimatur (Latin for 'let it be printed') is an official declaration by a competent ecclesiastical authority — usually a bishop or his delegate — that a book, pamphlet, or other written work may be published because it contains nothing contrary to Catholic faith or morals. Originally a requirement of the Catholic Church's canon law, the term has been adopted more broadly to denote any authoritative approval or endorsement, especially of printed matter.1
The practice of pre-publication review by church authorities dates to the early Church, but the formal requirement of an imprimatur was established by the Fifth Lateran Council (1512–1517) in response to the spread of printed heresies during the Reformation.2 The council decreed that no book could be printed without prior examination and approval by the local bishop. This was later codified in the 1917 Code of Canon Law and retained in the 1983 revision. The principal purpose is to protect the faithful from doctrinal error and moral harm, while also preserving the integrity of ecclesiastical teaching. The process involves two steps: first, a nihil obstat ('nothing hinders') from a designated censor, then the imprimatur itself from the bishop or his vicar general. The censor's report is confidential, and the bishop may withhold or revoke the imprimatur if he finds serious defects.3
Under current Catholic canon law, the imprimatur is required for several categories of publications: (1) books of Sacred Scripture, catechisms, liturgical books, and textbooks on theology, canon law, church history, or moral/religious subjects intended for use in Catholic schools or seminaries; (2) writings on religious matters by clerics or members of religious institutes; and (3) any other works that the bishop judges necessary for the protection of faith and morals.4 The imprimatur does not imply that the bishop agrees with every opinion expressed, only that nothing in the work contradicts Catholic teaching. In practice, many Catholic publishers now rely on the imprimatur of the local bishop where the work is published. The requirement is less strictly enforced today than in the past, but it remains a canonical obligation. Some traditionalist and independent Catholic groups have continued to seek imprimaturs, while others have rejected the practice as an infringement on religious freedom.5
Beyond its familiar role in Catholic publication, the imprimatur has a number of lesser-known dimensions. The term was historically used by the British monarchy: royal grants of printing privileges in the 16th and 17th centuries were sometimes styled as 'imprimatur' under the royal prerogative, effectively controlling the press. In the 20th century, the concept was invoked in secular contexts: for example, the 'imprimatur' of the U.S. Food and Drug Administration for drug labels, or the 'imprimatur' of a university press for scholarly monographs, although these uses are metaphorical.6 A notable edge case is the imprimatur granted to works of fiction, such as Graham Greene's The Power and the Glory (1940), which was initially condemned by the Holy Office but later received a grudging imprimatur after revisions. The censor's report for that book, discovered in Vatican archives, reveals that the bishop personally intervened to allow publication despite the censor's objections. Another obscure fact: the imprimatur can be revoked even after publication if new information reveals doctrinal error; this happened in 2011 when the Congregation for the Doctrine of the Faith withdrew the imprimatur from a textbook on moral theology by Father Marciano Vidal.7
Outside the Catholic Church, the word 'imprimatur' is commonly used to mean any official approval or endorsement, especially of a book, statement, or policy. In the publishing industry, it is often applied to the seal of approval from a reputable editor or publisher, signifying that the work meets certain standards. In law, an 'imprimatur' may refer to a court's approval of a settlement or a government agency's clearance of a product. The term appears in the United States Constitution's First Amendment debates: opponents of prior restraint argued that requiring an imprimatur for publication was a form of censorship. In the digital age, the concept has been revived in discussions of content moderation: some propose that platforms like Facebook or Twitter should require an 'imprimatur' for verified accounts or news sources. However, these uses are not formal and vary widely in meaning.8 The metaphorical extension has made 'imprimatur' a common term in business and politics, often used to lend authority to a project or idea.
The term 'imprimatur' is sometimes used incorrectly as a synonym for 'nihil obstat'; the two are distinct steps in the approval process.
