Novena prayer to the Holy Ghost

We ought to pray and invoke the Holy Spirit, for each of us greatly needs His protection and His help. The more a man is deficient in wisdom, weak in strength, borne down with trouble, prone to sin, so ought he the more fly to Him Who is the never ceasing Fount of Light, Strength, Consolation and Holiness." - Pope Leo XIII

Prayer for the Seven Gifts of the Holy Ghost

O Lord Jesus Christ Who, before ascending into heaven, didst promise to send the Holy Ghost to finish Thy work in the souls of Thy Apostles and Disciples, deign to grant the same Holy Spirit to me that He may perfect in my soul the work of Thy grace and Thy love. Grant me the Spirit of Wisdom that I may despise the perishable things of this world and aspire only after the things that are eternal; 

the Spirit of Understanding to enlighten my mind with the light of Thy divine truth; 

the Spirit of Counsel that I may ever choose the surest way of pleasing God and gaining heaven; 

the Spirit of Fortitude that I may bear my cross with Thee and that I may overcome with courage all the obstacles that oppose my salvation; 

the Spirit of Knowledge that I may know God and know myself and grow perfect in the science of the Saints; 

the Spirit of Piety that I may find the service of God sweet and amiable; 

the Spirit of Fear that I may be filled with a loving reverence towards God and may dread in any way to displease Him. Mark me with the sign of Thy true disciples and animate me in all things with Thy Spirit. Amen.

Come, Holy Ghost (prayer)

Veni, Sancte Spiritus, reple tuorum corda fidelium: et tui amoris in eis ignem accende. V. Emitte Spiritum tuum, et creabuntur. R. Et renovabis faciem terrae. Oremus. Deus, qui corda fidelium Sancti Spiritus illustratione docuisti: da nobis in eodem Spiritu recta sapere; et de eius semper consolatione gaudere. Per Christum Dominum nostrum. Amen.

Come, Holy Ghost, fill the hearts of Thy faithful, and kindle in them the fire of Thy love. V. Send forth Thy Spirit, and they shall be created. R. And Thou shalt renew the face of the earth. Let Us Pray O God, Who hast instructed the hearts of the faithful by the light of the Holy Ghost, grant that by the same Spirit we may be always truly wise, and ever rejoice in His consolation. Through Christ our Lord. Amen.
