4 Whether all oathes are to be kept.
OATHES conceiued or made rightlie of thinges lawfull, true, certaine, waightie, and possible, are to be kept. For if once thou hast acknowledged and testified thy selfe to bee iustly bound to keepe thy promise, and hast called god to record hereof, when as afterwards thou wittingly and wil∣lingly breakest thine oath, thou doest violate and breake a iust bonde, and doest either accuse god, the witnes and maintainer of this bond, of vanity and lightnes, or prouoke him to punish thee. Psal. 15.4.5. He that sweareth to his owne hinderance and changeth not, shall neuer be moued. Numb. 30.3. Whosoeuer voweth a vowe vnto the Lord, or sweareth an oath to bind himselfe by bond, hee shall not breake his promise, but shall doe according to all that proceedeth out of his mouth.
But oathes that are male of vnlawful thinges, either by an er∣ror, or by ignoraunce, or through infirmitie, or against the consci∣ence, it is sinne to keepe them. And therefore such oaths are to be retracted and recalled, least we adde thereby sinnes vn∣to sinnes. For he that keepeth an oath made of vnlawful things, heapeth sinne vpon sinne, both in that he sware, and so hath a wil to sinne, and also in that he endeuoureth to do that which he sware, and so confirmeth that will of sinning by an oath. For what thinges GOD forbiddeth, those thinges hee will not haue men either sworne or vnsworne to perfourme: and what hee forbiddeth vs to will, or promise, or sweare, so much the more doth hee forbidde vs to doe the same, how much the more grieuous a thing it is to doe them, than to will or promise them. They therefore who keep that which they haue ill sworne, heape sinne vnto sinne; as did Herod putting Iohn Baptist to death by pretence of keeping his oath: and likewise such as keepe monastical vowes, where∣by they haue sworne Idolatrie, and impious single liuing. Neither is this argument of any force: An oath is necessarilie to be kept, but they haue sworne these thinges: therefore they must needes keepe them. For the Maior is true of a lawfull oath. But an oath, which is made of a thing forbidden by god, is not to be kept: because it is not a lawful oath; which also is
