佛祖統紀 26.5

26.5

（四明石芝曉法師。取異代同修淨業功德高盛者立為七祖。今故遵之。以為淨土教門之師法焉）。

(Dharma Master Shizhi Xiao of Siming selected those from different generations who jointly cultivated pure karma with lofty and flourishing merit, establishing them as the Seven Patriarchs. We now follow this, taking them as a model for the Pure Land teaching.)
