The Lord's Prayer in Church Slavonic, as presented by Kedrov:

Отче нашъ, иже еси на небесехъ, 
да свѧтитьсѧ имѧ Твое, 
да прiидетъ царствiе Твое. 
Да бѫдетъ воля Твоя яко на небеси и на земли. 
Хлѣбъ нашъ насѫщьнъ даждь намъ дьньсь, 
и остави намъ длъгы нашѧ, 
якоже и мы оставляемъ длъжникомъ нашимъ. 
И не въведи насъ въ искушенiе, 
нъ избави насъ от лѫкавого. 
Аминь.
Anglicised transliteration:

Otche nash, izhe yesi na nebesekh,
da svyatitsya imya Tvoye,
da priidet tzarstviye Tvoye.
Da budet volya Tvoya yako na nebesi i na zemli.
Khleb nash nasushchni dazhd nam dnes,
i ostavi nam dolgi nasha
yakozhe i mi ostavlayem dolzhnikom nashim.
I ne vedi nas vo iskusheniye,
no izbavi nas ot lukavago.
Amin.

English (Common Prayer version)

Our Father, which art in heaven,
hallowed be thy name;
thy kingdom come;
thy will be done in earth as it is in heaven.
Give us this day our daily bread.
And forgive us our trespasses,
as we forgive them that trespass against us.
And lead us not into temptation;
but deliver us from evil.
Amen.
