The Word Hypoftafis is Greek* u'wawf, Subfiftentia 5 compounded of c'-nu, fub, under, and 'imp*, or &&, fto,exifto,

The Term Hypoftafis is of a very ancient (landing in the Church. St. Cyril repeats it divers Times, as alio the Phrafe Union according to Hypoftafis. The firft. Time itoccurs in all Chriftian Antiquity, is in a Letter of that Father to Neftorius, where he ufes it inftead of w^opmv, the Word we com- monly render Perfon, which did not feem exprefiive enough. " The Philofophers, fays St. Cyril, have allow'd three Hy- u poftafes : They have extended the Divinity to three ffly- " poftafes ■ They have even fometimes ufed the Word Tri- tf nity : Aiid nothing was wanting but to have admitted the " Confubftantialitv of the three Hypoftafes, to mew the
II Unity of the divine Nature, exclusive of all Triplicity « in refpe6t of Diftincfion of Nature, and not to hold it " necefTary to conceive any refpe&ive Inferiority of Hv- « poftafes." 3 J
This Term occafion'd great DifTentions in the ancient
Church ; firft among the Greeks, and afterwards alio among the Latins,
In the Council of Nice, Hypoftafis was defln'd to de- note the fame with Ejfence or Subftance 5 fo that it was Herefy to fay that Jefus Chrift, was of a different Hypojiafis from the Father ; but Cuftom alter'd its Mean- ing. — In the Neceffity rhey were under of exprefling themfelves ftrongly againlt the Sabellians, the Greeks made Choice of the Word Hypcfiafis, and the Latins ofPerfona$ which Change prov'd the Occafion of endlefs Difagreement. Thofe who took the Word Hypoftafis in its ancient Signifi- cation, could not bear to hear of three Hypoftafes, which, according to them, were ib many divine EfTences or Sub- ftances. And yet they who ufed the Word in the new Senfe againlt. the Sabellians, all along declar'd, that they meant by it three Individuals, or three Subjecls which fub- fift alike, and not three different Effences or Subftances : So that in their Senfe, they admitted three Hypoftafes in one and the lame EfTence.
Others, by EfTence, underftood a common and indefinite Nature, as Humanity is to all Men in the general ; and by Hypojiafis, a tingle Nature, peculiar to each Individual, as each Man in particular is a Modification of the whole human Nature or EfTence — But this laft Signification, which fome attribute to St, 'Baftl, if apply 'd to the Deity, would im- ply Trirheifm : For if the three Perfbns in the Trinity be three Hypvftafes, juft as 'Peter, James, and John are, there are manifeftly three Gods.

HYPOTHECA, in the Civil Law, an Obligation, where- by the EfFecls of a Debtor are made over to his Creditor, . to fecure his Debt : The fame with Mortgage in the Com- mon Law. See Mortgage,
As the Hypotheca is an Engagement procur'd on Purpofe for the Security of the Creditor, various Means have been made ufe of to fecure to him the Beiufit of the Convention. The Ufe of the Pawn or Pledge is the mo ft ancient ; which is almoft the fame Thing with the Hypotheca ; all the Dif- ference confiding in this, that the Pledge is put into the Creditor's Hands ; whereas, in a fimple Hypotheca, the Thing remain'd in the Poffelfion of the Debtor. It was found more cafy and commodious to engage an Eftate by a fimple Covenant, than by an actual Delivery : Accordingly the Expedient was firft praclis'd among the Greeks ; and from them the Romans borrow'd both the Name and the Thing; only the Greeks, the better to prevent Frauds, ufed to affix fome vifible Mark on the Thing, that the Publick might know it was morrgag'd by the Proprietor : But the Romans, looking on fuch Adverrifemcnts as injurious ro the Debtor, forbad the Ufe of them.
The Roman Lawyers diftinguifii'd four Kinds of Hypc- tfceca's : The Conventional, which was with the Will and Confent of both Parties; The Legal, which was ap- pointed by Law, and for that Realbn call'd Tacit : The c PrcCtor\ £ Pledge, when by the Flight or Non-appearing of the Debtor, the Creditor was put in PofTeffion of his Effects : And the Judiciary, when the Creditor was put in PofTeftion by Virtue of a Sentence of the Court.
The Conventional Hypotheca is fubdivided into general and fpecial. The Hypotheca is general \ when all the Deb- tor's Effects, both prefent and future, are engag'd to the Creditor, It is fpecial, when limited to one or more parti- cular Things.
For the tacit Hypotheca, the Civilians reckon no lefs than 26 different Species thereof.
The Word comes from the Greek, Jm>5«V«, a Thing fub- je&ro force Obligation; of the Verb UTivn&yMt, fupponor, I am fubjecled ; of 77-^r, pono, I put.
