佛祖統紀 4.48

4.48

世尊滅後百年。毘舍離城。跋闍子比丘。擅行十事聽兩指抄食。得聚落間。得寺內。後聽可。得常法。得受金銀。彼於布薩日。檀越有施金銀。而共分之。如是簡擇一一檢校。乃至十事非法。非毘尼非佛所教。七百阿羅漢。集論法毘尼。故名七百結集（四分律）。

One hundred years after the extinction of the World-Honoured One, in the city of Vaiśālī, the Vṛjiputraka monks arbitrarily practiced ten points: permitting taking food with two fingers; taking food between villages; taking food inside a monastery; subsequent permission; standard practice; and receiving gold and silver. On the poṣadha day, when donors gave gold and silver, they divided it among themselves. In this way, each item was examined and inspected one by one, up to the conclusion that the ten points were contrary to the Dharma, contrary to the Vinaya, and not what the Buddha taught. Seven hundred arhats assembled to discuss the Dharma and Vinaya; hence it is called the Council of Seven Hundred (*Four-Part Vinaya*).
