PIB Arlington adheres to the following Statement of Faith:
- The inspiration and authority of the Bible (Old and New Testaments) as the full revelation of God by the Holy Spirit.
- The Deity of the Lord Jesus Christ, His virgin birth, His substitutionary atoning death on the cross, His bodily resurrection, and His personal return.
- The necessity of the new birth for entering the Kingdom of God, as described in John 3, followed by biblical water baptism through immersion as described in Romans 6:4, and Jesus' own example described in Matthew 3:13-17.
- The obligation upon all believers to be witnesses of the Lord Jesus Christ and to seek the salvation of others.
