The doctrinal views of the UPCI movement, with the exception of the 'Second work of grace' embraces the Pentecostal view that speaking in tongues is the initial sign of receiving the Holy Spirit.

The UPCI holds a fundamental view of the Bible.The UPCI rejects all extrabiblical revelations and writings, and views church creeds and articles of faith only as the thinking of men.

The UPCI holds that salvation is by grace through faith in Jesus Christ, not by works. Faith in Jesus is the means by which a person is justified. At the same time, a sinner must believe the gospel; he is commanded to repent of his sinful life, to be baptized in water in the name of Jesus Christ, and to receive the gift of the Holy Spirit.Thus the various aspects of faith and obedience work together in God's grace to reconcile us to God.

In distinction to the doctrine of the Trinity, the UPCI holds to a oneness view of God. It views the Trinitarian concept of God as inadequate and a departure from the consistent and emphatic biblical revelation of God being one.

The UPCI teaches that the one God who revealed Himself in the Old Testament as Jehovah revealed himself in His Son, Jesus Christ. Thus Jesus Christ was and is God. In other words, Jesus is the one true God manifested in flesh, for in Him dwells all the fullness of the God-head bodily.

While fully God, Jesus was also fully man, possessing a full and true humanity. He was both God and man. Moreover, the Holy Spirit is God with us and in us. Thus God is manifested as Father in creation and as the Father of the Son, in the Son for our redemption, and as the Holy Spirit in our regeneration.

Christian water baptism is an ordinance instituted by Jesus Christ. If it is not important in the plan of God, why did Jesus command it in Matthew 28:19? And why did Peter follow up by saying, "Be baptized every one of you," and by commanding the Gentiles to be baptized.

We must remember two points about the importance of water baptism. First, whatever Christ definitely established and ordained cannot be unimportant, whether we understand its significance or not. Second, Christ and the apostles showed the importance of this ordinance by observing it. Jesus walked many miles to be baptized, though He was without sin, saying, "For thus it becometh us to fulfill all righteousness"

It is true that water itself does not contain any saving virtue, but God has chosen to include it in His plan of salvation. Peter explained, "Baptism doth also now save us". According to Luke 7:30, "the Pharisees and lawyers rejected the counsel of God against themselves, being not baptized."

According to the Scriptures, the proper mode of baptism is immersion. A corpse is not buried by placing it on top of the ground and sprinkling a little soil on it, but by covering it completely.

According to the World Book Encyclopedia immersion was not convenient after the Catholic church instituted infant baptism; thus the mode was changed to sprinkling.

Repentance identifies us with the death of Christ, and baptism identifies us with His burial. Coming forth from the watery grave of baptism and receiving new life in the Holy Spirit identifies us with His resurrection.

All Scripture is given by inspiration of God, and is profiTABLE for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work.
