Answer:
Assembly of God is a "Trinitarian" denomination of the Pentecostal / Holiness faith. Other Pentecostal denominations are Church of God and Church of God of Prophecy, as well as many other Full Gospel independent non denominational Churches under many different names of their own choosing. Examples would be Spring Hill Pentecostal Church or Holiness Tabernacle. "Oneness" Pentecostal denominations such as the Apostolic Church or the United Pentecostal Church, and some other Jesus Name Only groups teach that the name "Lord Jesus Christ" is (THE NAME - not -THESE NAMES) of the Father (Lord), Son (Jesus), and Holy Ghost (Christ), which is to be used in baptism (immersion). Compare Jesus' instructions for baptism in the Gospels with the Apostles method (Acts 2:38), and remember that Jesus often spoke in parables. So teaching that God is only 1 single person (being) manifested as Father (God in Heaven), Son (God in Christ), and Holy Ghost - (Christ in You) NOT 3 separate persons in 1 God (Trinity). Oneness vs Trinity - I AM THAT I AM vs WE ARE THAT I AM. Since the word TRINITY isn't in the Bible I tend to agree with the Oneness groups, although I'm not sure of every body's theology, PERSONALLY, my understanding is that God in Heaven, the Father, is spirit (Holy Spirit), is 1 person not 2. He was manifested - not incarnated - in Jesus (Son of God - not God the Son). Jesus being the second Adam - made in the Image of God - as the express image of the invisible God has come in GOD'S NAME and is recognized as God. "I can of my own self do nothing, but what I see the Father do, that I do also for it is not I that do these things but it is my Father in me". "I and the Father are One for He is in Me and I am in him, even so I pray that the Father and I can come into you and you can come into Us so that We may become ONE even as I and my Father are ONE". God in Christ and Christ in You, the hope of Glory. God is One Spirit, the Father (Holy Ghost), in Jesus, and the Church instead of three people as one God. Most Pentecostals as a general rule believe in Holiness (conservative life style and dress) as opposed to Charismatics who most Pentecostals consider to dress and act like clowns. Pentecostals and Charismatics both believe in Tongues, Prophecy, Miracles and Divine healing.
