10.261

景云：我今欲於善男子所者，於出家無受菩薩戒者遍求戒。或長老所者，於出家小者。或大德所者，出家大者，今尋律藏善見律云：老者而言大德，小者而稱長老，首律師云：此亦不定，謂四分律內牽他出房戒中，十七群書小六群而語六群言，長老是我等上座。又五百結集中離波多喚一切去最大上座作大德長老。十誦律云：從今不得直喚上座為長老，應言長老某甲，如喚長老舍利弗目連等。

Jing says: 'I now wish to go to a good son' refers to seeking precepts everywhere among those who have gone forth but have not received the bodhisattva precepts. 'Or to an elder (āyuṣmat)' refers to junior renunciants. 'Or to a venerable one (bhadanta)' refers to senior renunciants. Now examining the Vinayapiṭaka, the Samantapāsādikā says that seniors are called 'venerable ones' and juniors are called 'elders'. Vinaya Master Shou says: this is also not fixed; for example, in the precept on dragging another out of a cell in the Dharmaguptaka Vinaya, the group of seventeen junior monks said to the group of six: 'The elders are our seniors.' Furthermore, at the Council of the Five Hundred, Revata called the foremost senior who had gone beyond all others 'venerable elder'. The Sarvāstivāda Vinaya says: 'From now on, do not directly call a senior merely an elder; you should say "Elder so-and-so", as when calling Elder Śāriputra, Maudgalyāyana, and so forth.'
