Catholics say that their involvement with charismatic renewal has revitalised their faith and led them to a deeper devotion to Christ in the Eucharist and a fuller appreciation of the liturgy. Theological foundations Renewal advocates believe that the charisms identified in Saint Paul's writings, especially in , , and , continue to exist and to build up the Church (see Catechism of the Catholic Church, §2003). The nine charismatic gifts considered extraordinary in character include: faith, expression of knowledge and wisdom, miracles, the gift of tongues and their interpretation, prophecy, discernment of spirits and healing.() These gifts are related to the traditional seven gifts of the Holy Spirit described in (wisdom, understanding, counsel, fortitude, knowledge, piety, and fear of the Lord, as listed in Catechism of the Catholic Church, §1831).

They were introduced to two books, The Cross and the Switchblade and They Speak with Other Tongues, which emphasized the Holy Spirit and the Spirit's charisms. In February 1967, Storey and Keifer attended an Episcopalian prayer meeting and were baptized in the Holy Spirit. The following week, Keifer laid hands on other Duquesne professors, and they also had an experience with the Spirit. Then, in February, during a gathering of Duquesne University students at The Ark and The Dove Retreat Center north of Pittsburgh, more people asked Keifer to pray over them. This led to the event at the chapel where they too received the Holy Spirit and spoke in tongues, as well as many other students who were present in the chapel. Keifer sent the news of this event to the University of Notre Dame, where a similar event later occurred, and the Renewal began to spread. While the Catholic hierarchy was initially reticent about these developments, Pope Paul VI officially welcomed Catholic charismatics in 1975. Expansion Adherents of the movement formed prayer groups and covenant communities. In these communities, members
