- Here is the section from the Editio Critica Major about their criteria when citing church fathers:"The difficulty of distinguishing true quotations from allusions or paraphrases is well known. Considering the great mass of the variant readings found in the manuscript tradition of the first millenium and recorded in the present edition, the following rule of thumb is observed:
a true quotation is one where the wording of the Father's text is identical with a reading found in the manuscript tradition. Readings attested exclusively by a Father are only rarely recorded. Allusions are considered only if they clearly reflect a known reading. Variants are excluded from the apparatus if they may be ascribed to a Father's stylistic tendencies and are unlikely to have been in his manuscript source. In essence, the criteria for patristic quotations are restrictive in order to ensure their reliability. Patristic quotations are identified in the apparatus by abbreviations of the Fathers' names. The same Father may be cited in support of more than one reading when the Father quotes the text in more than one form.
...In the apparatus the following symbols are used with reference to patristic quotations:
V ut videtur: the quotation is cited in support of a particular reading although its wording is not identical with it. This symbol is used in the apparatus only when the evidence in the Father's writings for a reading is not definitive."David Robert Palmer
