Speaking in (with) other tongues—languages (magnifying God through uttering His wonderful works in languages normally unknown to the speaker—Acts 2:4–8; 11; 10:44–46) is common in the Book of Acts to describe the coming of the Holy Spirit upon believers as clearly stated in the foregoing scriptural texts. Acts 19:6 also shows the same result (speaking in tongues and prophesying) when the apostle Paul laid hands on twelve believers in the city of Ephesus for them to receive the Holy Spirit. In regulating the order and use of spiritual gifts to the Corinthian saints (1 Corinthians 12–14), Paul also allows for the private use of tongues in prayer to God and indicates that this edifies the individual believer ’s spirit (14:2–4). The gifts of tongues and interpretation of tongues for public use in the assembled congregation are, of course, to be distinguished from the baptism with the Spirit as applied in the individual’s experience. Paul makes this clear by referring to his own experience (cf. Acts 9:17–19) when he says, “I thank my God, I speak with tongues more than ye all” (1 Corinthians 14:18). While closing his admonition by prioritizing the gift most useful for the public edification of all (prophecy), he was careful to add, “and forbid not to speak with tongues” (v. 39).
Following the biblical pattern in Acts, the Church of God of Prophecy and other classical Holiness/Pentecostal churches teach that speaking with other tongues as the Spirit gives utterance is the initial evidence (observable by others) of the baptism with the Holy Spirit. However, it is not to be regarded or sought as an “end-all” experience. Daily walking and living in the Spirit (Romans 8:1–14) will continue to build Christian character (the fruit of the Spirit) and should be the desire and practice of every believer.
