Sutta References on Future Monks
In the future, Ananda, there will be clan-members [(religious) lineage members] who are “yellow-necks,” immoral, of bad nature. People will give them gifts for the sake of the sangha. Even then, Ānanda, I say, an offering made to the sangha is immeasurable. And, Ānanda, I say that in no way is an individual gift ever more fruitful than an offering made to the sangha.
