7 “As He spoke these words, many believed on Him.” Would that, while I speak also, many, who before this were otherwise disposed, understood and believed on Him! For perhaps there are some Arians in this large assembly. I dare not suspect that there are any Sabellians, who say that the Father Himself is one with the Son, seeing that heresy is too old, and has been gradually eviscerated. But that of the Arians seems still to have some movement about it, like that of a putrefying carcass, or certainly, at the most, like a man at the last gasp; and from this some still require deliverance, just as from that other many were delivered. This province, indeed, did not use to have such; but ever since the arrival of many foreigners, some of these have also found their way to our neighborhood. See then, while the Lord spoke these words, many Jews believed on Him. May I see also that, while I am speaking, Arians are believing, not on me, but with me!
