Catena Aurea on Mark 9:38–42: Augustine of Hippo

By which He shews, that he of whom John had spoken was not so far separated from the fellowship of the disciples, as to reject it, as a heretic, but as men are wont to hang back from receiving the Sacraments of Christ, and yet favour the Christian name, so as even to succour Christians, and do them service only because they are Christians. Of these He says they shall not lose their reward; not that they ought already to think themselves secure on account of this good will which they have towards Christians, without being washed with His baptism, and incorporated in His unity, but that they are already so guided by the mercy of God, as also to attain to these, and thus to go away from this life in security.
