The Church of the Nazarene believes that the Holy Spirit bears witness to the new birth and to the subsequent work of heart cleansing, or entire sanctification, through the infilling of the Holy Spirit.

We affirm that the one biblical evidence of entire sanctification, or the infilling of the Holy Spirit, is the cleansing of the heart by faith from original sin as stated in Acts 15:8–9: “God, who knows the heart, showed that he accepted them by giving the Holy Spirit to them, just as he did to us. He made no distinction between us and them, for he purified their hearts by faith.” And this cleansing is manifested by the fruit of the Spirit in a holy life. “But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control. Against such things there is no law. Those who belong to Christ Jesus have crucified the sinful nature with its passions and desires” (Galatians 5:22–24).

To affirm that even a special or any alleged physical evidence, or “prayer language,” is evidence of the baptism with the Spirit is contrary to the biblical and historic position of the Church. (2009)
