To end the schism caused by the refusal of the Eustathian or old Catholic party to recognise Meletius as bishop of the whole orthodox body.  The churches of the West and Egypt, on the whole, supported Paulinus, who had been ordained by Lucifer of Cagliari, bishop of the old Catholics.  The Ben. Ed. supposes the word οἰκονομῆσαι, which I have rendered “control,” to refer to Paulinus.  The East supported Meletius, and if the οἰκονομία in Basil’s mind does refer to Paulinus, the “management” meant may be management to get rid of him.
