Sermon on Law and Grace

The Sermon on Law and Grace (Old Church Slavonic: Слово о законѣ и благодѣти, Slovo o zakone i blagodeti) is a sermon written by the Kievan Metropolitan Hilarion. It is one of the earliest Slavonic texts available, having been written several decades before the Primary Chronicle. Since Hilarion was considered to be a writer worthy of imitation, this sermon was very influential in the further development of both the style and content of Kievan Rus' literature.

The Sermon was an important event to be mentioned in the Primary Chronicle, and by matching against other events from the Chronicle it was concluded that the Sermon was written somewhere between 1037 and 1050.

Although commonly called the Sermon on Law and Grace, the work bears a much longer title:

The sermon is divided into two distinct parts.

The first part presents the Grace of the New Testament surpassing and replacing the Law of the Old Testament. Hilarion retells the Old Testament account of Hagar, the handmaiden of Abraham, and Sarah, his wife. He likens Isaac, "the free son of a free mother", to the followers of Christianity, and Ishmael, "a servant (not a truly free man)", to the Jews. Hilarion emphasizes that the Law came first, and then came Grace, just as Ishmael came before Isaac. He then explains that the Gospel now spreads over the whole earth, while the "lake of the Law" has dried up.
