Pentecostal beliefs differ from one Pentecostal church to the next, since there is not one single central organization which directs the churches identifying themselves with Pentecostalism.
For instance, some churches identifying themselves with Pentecostalism are Nontrinitarian, while others are Trinitarian – that is, that God is a Trinity or Triune God, existing as Father, Son, and Holy Spirit in one Godhead.
Still, there are a few core set of beliefs which distinguish the Pentecostal faith from other Christian denominations, so let me spell those out.
Beliefs Most Pentecostals Share
Celebration of the Pentecost, when the Holy Spirit descended upon the followers of Jesus Christ, in the days after his martyrdom. (Depicted in the second chapter of Acts)
Personal Experience of God through connection (Baptism) in the Holy Spirit.
Evocation of the Teachings, Spiritual Power and Worship Styles of the early Christian church.
“Charismatic” signs of faith, such as Speaking in Tongues, Interpretation of Tongues, Prophecy, Faith Heling, and Discernment of Spirits.
Therefore, Pentecostal beliefs revolve around the idea that the Holy Spirit is just as involved in the lives of today’s Christians as it was in the lives of Jesus’ followers.
