四分律比丘含注戒本 1.13

1.13

At that time, there were those who recited the precepts with different factions of fellow teachers and acquaintances. The rule is that they should respect and serve them, reverently observe poṣadha, and recite the precepts dwelling together in concord in one place; violators incur an offense. The Buddha said that there are three kinds of concord: first, those who ought to come have come; second, those who ought to convey consent have conveyed consent; third, those who are present and entitled to protest do not protest. The opposite of this is a dissentient community.
