The month of May is often a month full of students receiving the Sacrament of Confirmation near the feast of Pentecost. Therefore, a prayer to the Holy Spirit seems very appropriate for us to learn / pray.
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.
