Matthew 12:30

He that is not with me. This sentence is not to be understood as directly spoken of heretics and schismatics, although at first sight it may appear so, but of the devil, who wishes to dead the souls of men captive, whilst Christ wishes to free them. He entices men to wickedness, Jesus Christ draws them to virtue: how therefore can the works of Christ be compared with those of Satan! (St. Jerome) --- There is no medium. We must either be with Christ, or against Christ: if we are not of Christ, whose then must we be, when nothing but sin can separate us from Christ and God? Oh, where will the generality of Christians, who shew themselves so indifferent with regard to salvation, find themselves at the last day? Can they say they are with Christ?
