This quote comes from Hilary, Bishop of Poitiers (+367). Ah, what joys of Pentecost!
We who have been reborn through the sacrament of baptism experience intense joy when we feel within us the first stirrings of the Holy Spirit. We begin to have an insight into the mysteries of faith, we are able to prophesy and to speak with wisdom. We become steadfast in hope and receive the gift of healing. Demons are made subject to our authority. These gifts enter us like a gentle rain, and once having done so, little by little, they bring forth fruit in abundance (Readings for the Daily Office from the Early Church, J. Robert Wright, ed. [Church Publishing Incorporated, 1991], p. 240).
