Christianity • Protestantism The Adventist Church of Promise (Portuguese: Igreja Adventista da Promessa or "IAP"[1]) is an evangelical Christian denomination which is both Sabbatarian Adventist and classical Pentecostal in its doctrine and worship.
It was founded in Brazil in 1932 by pastor John August Silveira (Portuguese João Augusto da Silveira), as a split-off from the Seventh-day Adventist Church.
It claims to be the first indigenous Brazilian Pentecostal denomination.
(The earlier Assemblies of God in Brazil were introduced from the United States).
Most of the church members live in Brazil, yet the church is also present in other countries: Argentina, Paraguay, Chile, Bolivia, Colombia, El Salvador, United States, Portugal, Spain, Nigeria, Mozambique, Cameroon and Uruguay.
