St Patrick, Bishop and Confessor
Patron of Ireland
The Lord made to him a covenant of peace, and made him a prince: that the dignity of the priesthood should be to him for ever. * O Lord, remember David: and all his meekness.
(Ecclesiasticus 45:30 and Psalm 131:1 from the Introit of Mass)
Deus, qui ad praedicandum gentibus gloriam tuam beatum Patricium Confessorem atque Pontificem, mittere dignatus es: ejus meritis et intercessione concede; ut, quae nobis agenda praecipis, te miserante adimplere possumus.
O God, who didst vouchsafe to send blessed Patrick, confessor and bishop, to preach Thy glory to the Gentiles, grant that, through his merits and intercession, we may be enabled to accomplish by Thy mercy, what Thou commandest us to do. Through our Lord.
