Psalms 91:12

Well, the Donatists are not false Christians. They are quite simply not Christians at all, since they listen to what the devil suggested and do not listen to the answer Christ gave him. How, after all, did the Lord, our teacher and savior, answer the devil's suggestion of such things? "Get back, Satan, for it is written: You shall not tempt the Lord your God." The devil, as a matter of fact, had taken his suggestion from Scripture, and the Lord replied from Scripture. The devil had said to the Lord, you see, "Since it is written, He will instruct his angels about you; they will lift you up in their hands, lest you should hurt your foot on a stone." "Hurl yourself down," he said, "and if you are the Son of God, the angels are there to catch you; what are you afraid of?" The Lord could indeed both have cast down his body and not allowed it to die; but what the devil was suggesting to Christ at that time is the sort of thing Christ was not teaching future Christians. This, you see, is exactly what the devil is also suggesting to the Donatists, saying, "Hurl yourselves down, the angels are there to catch you. With such a death you do not go to punishment, but you win through to a crown." They would be Christians if they give an ear to Christ and did not trust the devil, who first separated them from the peace of the church and later on gave them cliff-jumpers.

Let us return to the words of the Psalm. "They shall bear You in their hands, lest at any time Thou hurt Your foot against a stone" [Psalm 91:12]. Christ was raised up in the hands of Angels, when He was taken up into heaven: not that, if Angels had not sustained Him, He would have fallen: but because they were attending on their King. Say not, Those who sustained Him are better than He who was sustained. Are then cattle better than men, because they sustain the weakness of men? And we ought not to speak thus either; for if the cattle withdraw their support, their riders fall. But how ought we to speak of it? For it is said even of God, "Heaven is My throne." Because then heaven supports Him, and God sits thereon, is therefore heaven the better? Thus also in this Psalm we may understand it of the service of the Angels: it does not pertain to any infirmity in our Lord, but to the honour they pay, and to their service....What the finger of God is, the Gospel explains to us; for the finger of God is the Holy Ghost. How do we prove this? Our Lord, when answering those who accused Him of casting out devils in the name of Beelzebub, says, "If I cast out devils by the Spirit of God;" [Matthew 12:28] and another Evangelist, in relating the same saying, says, "If I with the finger of God cast out devils." [Luke 11:20] What therefore is in one stated clearly, is darkly expressed in another. You did not know what was the finger of God, but another Evangelist explains it by terming it the Spirit of God. The Law then written by the finger of God was given on the fiftieth day after the slaughter of the lamb, and the Holy Ghost descended on the fiftieth day after the Passion of our Lord Jesus Christ. The Lamb was slain, the Passover was celebrated, the fifty days were completed, and the Law was given. But that Law was to cause fear, not love: but that fear might be changed into love, He who was truly righteous was slain: of whom that lamb whom the Jews were slaying was the type. He arose from the dead: and from the day of our Lord's Passover, as from that of the slaying of the Paschal lamb, fifty days are counted; and the Holy Ghost descended, now in the fullness of love, not in the punishment of fear. [Acts 2:1-4] Why have I said this? For this then our Lord arose, and was glorified, that He might send His Holy Spirit. And I said long ago that this was so, because His…
