2667 This simple invocation of faith developed in the tradition of prayer under


many forms in East and West. The most usual formulation, transmitted by the

spiritual writers of the Sinai, Syria and Mt Athos, is the invocation, ‘Lord Jesus Christ, Son of God, have mercy on us sinners.’ It combines the Christological hymn of Philippians 2:6—II with the cry of the publican and the blind men begging for light.’8 By it the heart is opened to human wretchedness and the Saviour’s mercy.


2668 The invocation of the holy name ofJesus is the simplest way of praying

always. When the holy name is repeated often by a humbly attentive heart, the prayer is not lost by heaping up empty phrases,’9 but holds fast to the Word and ‘brings forth fruit with patience.’2° This prayer is possible ‘at all times’ because it is not one occupation among others but the only occupation: that of loving God, which animates and transfigures every action in Christ Jesus.


2669 The prayer of the Church venerates and honours the Heart ofJesus just as it

invokes his most holy name. It adores the incarnate Word and his Heart which, out of love for men, he allowed to be pierced by our sins. e loves


to follow the way of the cross in the Saviour’s steps. The stations from the

Praetorium to Golgotha and the tomb trace the way ofJesus, who by his holy Cross has redeemed the world.

‘Come, Holy Spirit’


2670 ‘No one can say “Jesus is Lord”, except by the Holy Spirit.’2’

Every time we begin to pray to Jesus it is the Holy Spirit who


draws us on the way of prayer by his prevenient grace. Since he

teaches us to pray by recalling Christ, how could we not pray to the Spirit too? That is why the Church invites us to call upon the


Holy Spirit every day, especially at the beginning and the end of

every important action. If the Spirit should not be worshipped, how can he divinize me through Baptism? If he should be worshipped, should he not be the object of adoration?22 2671 The traditional form of petition to the Holy Spirit is to invoke the Father through Christ our Lord to give us the Consoler Spirit.23 Jesus insists on this petition to be made in his name at the very moment when he promises the gift of the Spirit of Truth.24 But the simplest and most direct prayer is also traditional, ‘Come, Holy Spirit’, and every liturgical tradition has developed it in antiphons and hymns.
