金剛般若經依天親菩薩論贊略釋秦本義記卷上 1.118

1.118

經。爾時須菩提白佛言世尊當何名此經我等云何奉持　第四問答也。文復有四。一問二答三徵四釋。此初也。此中所以問答經名及受持者。以佛世尊嘆二處勝故。今明受持者。應先知名字及受持方法。是故於此尊處文中便申問答。當何名此經者。問經名也。我等云何奉持問受持方法也。

[Sūtra:] "At that time, Subhūti addressed the Buddha, saying: 'Bhagavat, by what name should this sūtra be called, and how should we uphold it?'"
This is the fourth [part], the questions and answers. This again has four parts: first, question; second, answer; third, inquiry; fourth, explanation. This is the first. Why are the name of the sūtra and its upholding asked and answered here? Because the Buddha, the Bhagavat, praised the superiority of the two places; now, to clarify upholding, one must first know the name and the method of upholding. Therefore, within this section on the honored place, the questions and answers are presented. "By what name should this sūtra be called" asks for the name of the sūtra. "How should we uphold it" asks for the method of upholding.
