Luke 1:51

(Photius.) Or she says, Hath showed, for will show strength, not as long ago by the hand of Moses against the Egyptians, nor as by the Angel, (when he slew many thousand of the rebel Assyrians,) nor by any other instrument save His own power, He openly triumphed, overcoming spiritual (intelligibiles) enemies. Hence it follows, he hath scattered, &c. that is to say, every heart that was puffed up and not obedient to His coming He hath laid bare, and exposed the wickedness of their proud thoughts.

In describing the state of mankind, she shows what the proud deserve, and what the humble; saying, He hath showed strength with his arm, &c. i. e. with the very Son of God. For as your arm is that whereby you work, so the arm of God is said to be His word by whom He made the world.

He has shown strength with His arm, He has scattered the proud in the imagination of their hearts. By His arm, He signifies the Son of God Himself. Not that God the Father is determined by the form of human flesh, and that the Son …

Or by this she means that they who fear shall obtain mercy, both in that generation, (that is, the present world,) and the generation which is to come, (i. e. the life everlasting.) For now they receive a hundred-fold, but hereafter far more. (Matt. 19:29.) For in His arm, that is, His incarnate Son, He hath showed strength, seeing that nature was vanquished, a virgin bringing forth, and God becoming man. This might also be understood of the Jews whom He scattered into all lands as they are now scattered.

Because the venerable mother of God taught that his mercy would come to be present for all those who feared him throughout the world, it remained for her to also suggest what those who were proud and who despised the warnings of truth would deserve. …

The arm of the Father is the Son; thus God the Father in His Son manifested authority and power over nature, for at the incarnation of the Son nature was overcome: a Virgin gave birth, God became man, and man became God. The Lord "scattered …

He hath wrought strength with his arm - That is, he hath shown the exceeding greatness of his power. She speaks prophetically of those things as already done, which God was about to do by the Messiah.

Hath showed strength with his arm - The “arm” is the symbol of strength. The expression in this and the subsequent verses has no particular reference to his mercy to Mary. From a contemplation of His goodness to her, she enlarges her views to a contemplation of His goodness and power in general, and to a celebration of the praises of God for all that he has done to all people. This is the nature of true piety. It does not terminate in thinking of God’s mercy toward ourselves.

His "Anointed," whose horn He will exalt (1Sa 2:10); in the Virgin's song, it is as the "Help" promised to Israel by all the prophets. My soul . . . my spirit--"all that is within me" (Ps 103:1).

These verses contain Mary's famous hymn of praise, in the prospect of becoming the "mother of our Lord." Next to the Lord's Prayer, perhaps, few passages of Scripture are better known than this. Wherever the Church of England's Prayer-book is used, this hymn forms part of the evening service. And we need not wonder that the compilers of that Prayer-book gave it so prominent a place. No words can express more aptly the praise for redeeming mercy which ought to form part of the public worship of every branch of Christ's Church. Let us mark, firstly — the full acquaintance with Scripture which this hymn exhibits. We are reminded as we read it, of many expressions in the book of Psalms. Above all, we are reminded of the song of Hannah , in first Samuel, chapter 2. It is evident that Mary's memory was stored with Scripture. She was familiar, whether by hearing or by reading — with the Old Testament. And so, when out of the abundance of her heart her mouth spoke, she gave vent to her feelings in Scriptural language. Moved by the Holy Spirit to break forth into praise, she chooses language which the Holy Spirit had already consecrated and used. Let us strive, every year we live — to become more deeply acquainted with Scripture. Let us study it, search into it, dig into it, meditate on it — until it dwells in us richly. (Colossians 3:16.) In particular, let us labor to make ourselves familiar with those parts of the Bible which, like the book of Psalms, describe the experience of the saints of old. We shall find it most helpful to us in all our approaches to God. It will supply us with the best and most suitable language both for the expression of our needs and thanksgivings. Such knowledge of the Bible can doubtless never be attained without regular, daily study. But the time spent on such study is never misspent. It will bear fruit after many days.

He hath showed strength - Or, He hath gained the victory, εποιησε κρατος. The word κρατος is used for victory, by Homer, Hesiod, Sophocles, Euripides, and others. With his arm - Grotius has well observed, that God’s efficacy is represented by his finger, his great power by his hand, and his omnipotence by his arm. The plague of lice was the finger of God, Exo 7:18. The plagues in general were wrought by his hand, Exo 3:20, And the destruction of Pharaoh’s host in the Red Sea, which was effected by the omnipotence of God, is called the act of his arm, Exo 15:16. He hath scattered - Διεσκορπισεν, hath scattered abroad; as a whirlwind scatters dust and chaff. The proud - Or haughty, ὑπερηφανους; from ὑπερ above, and φαινω I show - the haughty men, who wish to be noticed in preference to all others, and feel sovereign contempt for all but themselves. These God scatters abroad - instead of being in his sight, as in their own, the most excellent of the earth, he treats them as straw, stubble, chaff, and dust. In the imagination of their hearts - While they are forming their insolent, proud, and oppressive projects - laying their plans, and imagining that accomplishment and success are waiting at their right hand, the whirlwind of God’s displeasure blows, and they and their machinations are dissipated together.
