Luke 1:55

After a general mention of the Divine mercy and holiness, the Virgin changes the subject to the strange and marvelous dispensation of the new incarnation, saying, He has holpen his servant Israel, &c. as a physician relieves the sick, becoming visible among men, that He might make Israel (i.e. him who sees God) His servant.

That is, obedient and humble; for he who disdains to be made humble, cannot be saved.

For by Israel she means not Israel after the flesh, whom their own title made noble, but the spiritual Israel, which retained the name of faith, straining their eyes to see God by faith.

It might also be applied to Israel after the flesh, seeing that out of that body multitudes believed. But this he did remembering His mercy, for He has fulfilled what he promised to Abraham, saying, For in your seed shall all the nations of the earth be blessed. This promise then the mother of God called to mind, saying, As he spoke to out father Abraham; for it was said to Abraham, I will place my covenant, that I shall be your God, and the God of your seed after you.

But by seed he means not so much those who are begotten in the flesh, as those who have followed the steps of Abraham’s faith, to whom the Savior’s coming was promised for evermore.

For this promise of heritage shall not be narrowed by any limits, but to the very end of time there shall never lack believers, the glory of whose happiness shall be everlasting.
