四分律行事鈔資持記 3.757

3.757

五中，《五分》簡德，初引緣。破戒無行，邪見無慧，根不具無威儀。惡人得勢，謂假此興謗。佛下，立制。《伽論》選能。文明誦唄，例準說法，必取堪能。

In the fifth [part], the Pañcavargika selects according to virtue, first citing the causes. Breaking the precepts means lack of practice; heterodox views mean lack of wisdom; incomplete faculties mean lack of dignified demeanor. "Wicked persons gaining influence" refers to using this as a pretext to stir up slander. From "the Buddha" downwards, the rule is established. The Saṃghāvaśeṣa-śāstra selects capable ones. The text clearly mentions chanting hymns (pāṭha); by analogy with preaching the Dharma, one must choose those who are capable.
