 The Revival Centres was formed as a separate identity from the Commonwealth Revival Crusade in 1958, and at a short time later became a registered denomination pursuant to the Marriage Act 1961 (Cth), as Revival Centres of Australia.The Church has a strong emphasis on the need to show evidence of glossolalia or "speaking in tongues" to demonstrate receiving the Holy Spirit to be considered a full member of the Church and a saved Christian.Revival Centres International bases its glossolalia teaching on a literal interpretation of Acts 2, a trait with some other Pentecostal groups.
