四分律行事鈔資持記 3.1043

3.1043

第三斥非中，初標古。然下，正斥，初以理直破。一法，謂尼受白四，本制同秉，一眾不成；結界，本為攝人秉法，尼既同秉；無界則集人無準，法起無依，故云非界等。若下，次約法皮質。

In the third [section], refuting the errors: first, identifying the ancient [view]. From 'However...' onward is the formal refutation; first, directly refuting it through reasoning. 'A single act' means that for a nun receiving [ordination through] a jñapticaturbhā karmavācanā, the original prohibition required performing it together [in both saṃghas], and a single community does not suffice. Delineating a boundary is originally done to gather people and execute the legal act; since the nuns also perform it together, without a boundary there is no standard for gathering people and the legal act has nothing to rely upon; hence it says 'without a boundary', etc. From 'If...' onward is next refuting it through the legal procedure.
