大般涅槃經集解 25.14

25.14

案僧亮曰：三逆謗法不必有戒，其言破戒，此義云何？「若犯四重」至「名為破戒者」，明比丘害親謗法，其罪則重於在家。今云何但說破戒也。

Sengliang states: The three heinous sins and slandering the Dharma do not necessarily involve having precepts; as for calling them 'breakers of precepts', what does this mean? From 'if one commits the four grave offenses' to 'is named a breaker of precepts' clarifies that a monk harming kin and slandering the Dharma incurs a sin heavier than that of a householder. Why now does he only speak of breaking precepts?
