Definition
Onus episcopale (Latin: "episcopal burden" or "bishop's burden") refers to ancient customary payments made by the clergy to their diocesan bishop. These payments were not voluntary offerings but established obligations arising from long-standing ecclesiastical custom. The principal forms included synodals (payments made at synod gatherings), pentecostals (offerings tied to Pentecost, sometimes called Whitsun farthings), and similar dues owed by parish clergy to the bishop of the diocese in which they served.
The term belongs to the vocabulary of medieval canon law and ecclesiastical administration rather than to secular civil or common law. It describes a category of clerical financial obligation that helped fund the bishop's administrative functions and the costs associated with running diocesan governance.

Why It Matters in Research
This is a term of historical and ecclesiastical law. Researchers are most likely to encounter onus episcopale in three contexts: (1) pre-Reformation English ecclesiastical records, where such payments were actively assessed and collected; (2) treatises and digests on canon law and church governance; and (3) legal dictionaries and glossaries that preserve the vocabulary of ecclesiastical courts.
The term is nearly absent from modern legal practice. If it appears in a primary source, it is almost certainly a historical document — a church register, episcopal account book, visitation record, or pleading in an ecclesiastical court. Researchers working in English legal history prior to the sixteenth century should be alert to variant spellings and Anglicized paraphrases; scribes sometimes rendered the constituent payments (synodals, pentecostals) without using the umbrella Latin term.
One navigational trap: Black's Law Dictionary includes, immediately following its definition of onus episcopale, a statement about evidentiary burden — "if no evidence is adduced by the party on whom the burden is cast, the issue must be found against him." This is a fragment from a separate entry on onus probandi (burden of proof) that was typeset in proximity and has been misread as part of the onus episcopale entry. Researchers should not treat the evidentiary language as part of the definition of onus episcopale. The two concepts are entirely unrelated.
Corpus connections: researchers tracing the financial structure of the pre-Reformation English church may need to read onus episcopale alongside entries on advowson, tithe, first fruits, and Peter's pence, all of which describe different streams of ecclesiastical revenue and obligation. The dissolution of the monasteries and the English Reformation substantially disrupted or abolished many of these payments; post-Reformation sources will rarely use the term in a living legal sense.

Historical Dictionary Support
Black's, Rapalje & Lawrence, and Bouvier's are in complete agreement on substance: all three define onus episcopale as ancient customary payments from the clergy to the diocesan bishop, and all three identify synodals and pentecostals as the primary examples. The definitions are nearly verbatim across sources, suggesting a common derivation from earlier canonical glossaries.
None of the three dictionaries elaborates on the historical mechanism of collection, the basis in canon law for the obligation, or the manner in which these payments were assessed. They treat the term as self-explanatory to a nineteenth-century practitioner familiar with ecclesiastical law, which the modern researcher should not assume. For substantive treatment, sources in medieval church history and canon law — rather than legal dictionaries — will be more illuminating.
The Black's entry is the only one that mentions pentecostals as "pentecostals"; Bouvier's uses "pentacostals," a variant spelling common in older texts. Rapalje & Lawrence uses "&c." without specifying additional payment types. These minor differences are inconsequential to meaning but worth noting when tracing source lineage.

Jurisdictional Note
Onus episcopale was a feature of ecclesiastical law as administered in England and other jurisdictions under Roman Catholic and, later, Anglican church governance. It has no operative legal significance in American law, where the First Amendment separation of church and state and the absence of an established church eliminated any basis for civil enforcement of episcopal dues. Researchers in Scottish, Irish, or Continental ecclesiastical history will find analogous concepts under local canon law terminology.
