There are a variety of religious groups which call themselves "Apostolic" or use the term apostolic in reference to their members, such as The Apostolic Church International, a Pentecostal denomination borne out of a Welsh religious revival in 1904 and 1905. Another example of the use of the term "apostolic" is by the Roman Catholic Church, which traces its roots to the works of the Apostles of Jesus.
Created officially in 1915, the Apostolic Church began as a group of Pentecostals teaching that the gifts of apostles, prophets, evangelists, pastors and teachers found in the Book of Ephesians should operate in the church together with the nine gifts of the Holy Spirit promised in 1 Corinthians.
Oneness Pentecostal denominations such as the United Pentecostal Church also frequently refer to themselves as Apostolic Pentecostals. These groups deny the Trinity and claim that God, Jesus and the Holy Ghost are three distinct manifestations of one God simultaneously in existence. These Apostolic Pentecostals teach the importance of baptism "in Jesus' name" and the infilling of the Holy Ghost evidenced by speaking in other tongues.
The Catechism of the Catholic Church professes three ways in which the Church is Apostolic: its foundation is in the Apostles; the Church is the vessel for handing off the teachings of the Apostles; and bishops, thought of as the successors of the Apostles, guide the Church in unison with the Pope.
