四分比丘戒本疏 1.16

1.16

自下第二制其同法。僧體六和，羯磨義當同見、說戒義當同戒，餘之四和順成此二。由具六和功德大故，故諸教中聖菩薩等設敬禮僧，況餘凡下。然說戒時，四人已上須作單白廣說戒本。如此文中所辨者，是但三人已下須盡界集、不得受欲，對首展轉各各說云：「二大德一心念。今白月十五日（黑月隨稱）眾僧說戒。我比丘某甲清淨（三說）。」若但二人，直云：「大德一心念。」餘詞同上。若但一人，直對佛前云：「今白月」等，不須「大德一心念」言，餘詞同前。三人已下對首心念，通在自然作法諸界，隨依界集不說戒本。不同《明了論》對首等訖仍說戒本。僧說之中若有難事，又開三五略說之法。又說戒日，通於十四十五十六三日皆得，廣如律說。

From here below is the second [section], prescribing identical practices. The community's essence consists in the six harmonies: karmavācanā corresponds in meaning to harmony in views, while recitation of the prātimokṣa corresponds in meaning to harmony in precepts; the remaining four harmonies support and fulfill these two. Because possessing the six harmonies entails great merit, in all teachings holy bodhisattvas and others pay reverent homage to the Saṃgha, to say nothing of ordinary beings below them. However, at the time of the recitation of the prātimokṣa, four or more persons must perform a simple motion (ñatti) and extensively recite the prātimokṣa. As explained in this text, if there are only three persons or fewer, all must assemble within the boundary and may not receive [another's] consent (chanda); face-to-face, each in turn says: "Venerables, attend with single-mindedness. Today, on the fifteenth day of the bright fortnight (naming the dark fortnight accordingly), the community of monks performs the recitation of the prātimokṣa. I, the monk so-and-so, am pure" (spoken three times). If there are only two persons, one simply says: "Venerable, attend with single-mindedness," with the remaining words being the same as above. If there is only one person, directly before the Buddha one says: "Today, the bright fortnight..." and so forth, without needing the words "Venerable, attend with single-mindedness," with the remaining words being the same as before. For three persons or fewer, face-to-face and mental declarations are applicable throughout natural boundaries and ritually marked boundaries; assembling according to whichever boundary, they do not recite the prātimokṣa. This differs from the Vinayavibhāṣā, where, after face-to-face declarations and so forth are completed, they still recite the prātimokṣa. If there are difficulties during the community's recitation, an abbreviated recitation in three or five [sections] is also permitted. Furthermore, regarding the day for the recitation of the prātimokṣa, it is permissible on any of the three days—the fourteenth, fifteenth, or sixteenth—as extensively explained in the Vinaya.
