Vivadamulasutta 2.6

2.6

Yo so, bhikkhave, bhikkhu sandiṭṭhiparāmāsī hoti ādhānaggāhī duppaṭinissaggī, so sattharipi agāravo viharati appatisso, dhammepi agāravo viharati appatisso, saṅghepi agāravo viharati appatisso, sikkhāyapi na paripūrakārī hoti.

Such a mendicant lacks respect and reverence for the Teacher, the teaching, and the Saṅgha, and they don’t fulfill the training.
