12 But, moreover, in respect of what has been told you, that Cornelius communicates everywhere with those who have sacrificed, this intelligence has also arisen from the false reports of the apostates. For neither can they praise us who depart from us, nor ought we to expect to please them, who, while they displease us, and revolt against the Church, violently persist in soliciting brethren away from the Church. Wherefore, dearest brethren, do not with facility either hear or believe whatever is currently rumoured against Cornelius and about me.
