聖書神学
Glosses and other marginal notes were a primary format used in medieval Biblical theology and were studied and memorized for their own merit. Many Biblical passages came to be associated with a particular gloss, whose truth was taken to be scriptural. Indeed, in one case, it is generally reckoned that an early gloss explicating the doctrine of the Trinity made its way into the Scriptural text itself, in the passage known as the "three heavenly witnesses" or the "Comma Johanneum", which is present in the Vulgate Latin and the third and later editions of the Greek Textus Receptus collated by Erasmus (the first two editions excluded it for lack of manuscript evidence), but is absent from all modern critical reconstructions of the New Testament text, such as Westcott and Hort, Tischendorf, and Nestle-Aland.
