Troparion — Tone 4
Your Nativity, O Christ our God, / Has shone to the world the Light of wisdom! / For by it, those who worshipped the stars, / Were taught by a Star to adore You, / The Sun of Righteousness, / And to know You, the Orient from on High. / O Lord, glory to You!
Kontakion — Tone 3
Today the Virgin gives birth to the Transcendent One, / And the earth offers a cave to the Unapproachable One! / Angels with shepherds glorify Him! / The wise men journey with a star! / Since for our sake the Eternal God was born as a Little Child!
