The Holy Spirit is a sine qua non in the life of the church and in all Christian life and experience. The importance of the experiential and praxis-oriented theology of the Charismatic Renewal and Pentecostalism cannot be overemphasized in the realization of the potentials of a Spirit-animated church. In fact, Charismatic Renewal in the Nigerian Catholic Church is an essential part of the changing face of the Catholic Church in Nigeria. This work is, therefore, using Charismatic and Pentecostal theology and praxes to argue for the renewal of the Nigerian Catholic Church. It avers that the praxis-oriented and experiential theology of the Charismatics and Pentecostals, which characterize them as Spirit-filled groups and churches, are enabling the Nigerian Catholic Church to realize the potentials of a Spirit-driven church. It upholds that the Nigeria Catholic Church through the Nigerian Catholic Charismatic Renewal, which is an indispensable part of the changing face of the Catholic Church in Nigeria, has wittingly or unwittingly begun the renewal of her pneumatological, ecclesiological, and liturgical doctrines and practices in accord with those of a truly Spirit-animated church.
