Pius, admirable Shepherd, ever mindful of thy sheep, before the highest Judge do thou intercede for all believers. 

Let us pray.

O God, who in order to crush them that hate Thy Church and to restore Thy solemn worship, didst vouchsafe to choose Blessed Pius to be Thy great High Priest: grant us to be secure under his protection and so to continue Thy service,   that, having overcome all the wiles of our adversaries, we may enjoy a perpetual peace. Through Christ our Lord.

Amen.

Our Father, Hail Mary, Glory be.
