Come Holy Spirit, fill the hearts of your faithful and kindle in them the fire of your love.
V. Send forth your Spirit, and they shall be created.
R. And you shall renew the face of the earth.
Let us pray.
O God, by the light of the Holy Spirit you instructed 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.

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.
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.
