Day 1 of 9

The Holy Spirit himself — that he may come and dwell in the soul

From the Novena to the Holy Spirit (Pentecost Novena)

Sacred Scripture: John 14:16-17

Meditation for Day 1

The first day asks for the Holy Spirit himself. Jesus promised: 'I will ask the Father, and he will give you another Advocate, to be with you for ever.' The Apostles waited nine days for this promise; the novena asks the same Spirit to dwell anew in every soul that prays.

St. John Paul II, in Dominum et Vivificantem, writes that the Holy Spirit is 'the personal love of the Father and the Son.' The novena's opening day asks for the gift of that love.

Daily Novena Prayer (recited every day)

Veni Sancte Spiritus (Come, Holy Spirit)

Come, Holy Spirit, fill the hearts of your faithful and kindle in them the fire of your love. Send forth your Spirit and they shall be created. And You shall renew the face of the earth. O God, who by the light of the Holy Spirit, did instruct the hearts of the faithful, grant that by the same Holy Spirit we may be truly wise and ever enjoy His consolations, through Christ Our Lord. Amen.

This is the traditional collect for Pentecost, found in the Roman Missal and used as the daily closing of the novena.

Concluding prayers: Many novena traditions add one Our Father, one Hail Mary, and one Glory Be at the close of each day's prayer.
