The Order of St. Benedict
ALMIGHTY God, who through thine only-begotten Son Jesus Christ hast overcome death, and opened unto us the gate of everlasting life; We humbly beseech thee that, as by thy special grace preventing us thou dost put into our minds good desires, so by thy continual help we may bring the same to good effect; through* Jesus Christ our Lord, who liveth and reigneth with thee and the Holy Ghost ever, one God, world without end. Amen.
CHAPTER XV
At What Times the Alleluia Is to Be Said
From holy Easter until Pentecost let the Alleluia be said without intermission, both with the psalms and with the responsories; but from Pentecost until the beginning of Lent let it be said every night at the nocturns with the six latter psalms only. However, on all Sundays outside of Lent, let the canticles, Lauds, Prime, Tierce, Sext, and None be said with Alleluia. Let Vespers, however, be said with the antiphon; but let the responsories never be said with Alleluia, except from Easter to Pentecost.
"And they found the stone rolled away from the sepulchre. And they entered in, and found not the body of the Lord Jesus. " St. Luke 24:2-3
