user2390: Was there an incident in the Buddhist scripture where the Buddha said of the indebtedness of the unenlightened monks to the laity that they should at least generate metta? 

user295: This is covered in the Cūlaccharāsanghāta Sutta, this was preached to counter the  Aggikkhandhopama Sutta, which was said to frighten many monks back to lay life , or to "disrobe". This is supposedly (link) said in the Manorathapūranī, the commentary by Buddhaghosa on the Aṅguttara-nikāya.
