As posted in another board by an INC member-- forums.abs-cbn.com/index.php?showtopic=30144 , here are the basic beliefs of this sect:
**One God, the Father **
We believe that the one and only true God is the Father, the Creator. We hold this belief because it is the doctrine taught by our Lord Jesus Christ and His Apostles (John 17:3, 1: I Corinthians 8:6). God is a Spirit (John 4:24), and, therefore, He has no flesh and bones (Luke 24:39).
There is no trinity of persons in God. Though the Bible speaks of the Father, the Son, and the Holy Spirit, never does it refer to all of them as gods nor as three persons in one God; rather, it points to the Father alone as the true God. The Son Himself emphasized that only the Father is the true God (John 17:3, 1) and that He himself is a man telling the truth which He received from God (John 8:40). The prophets also teach that we have only one Father who created us (Malachi 2:10); Isaiah 64:4, 8). He alone is God, there is no other God and no one is like Him (Isaiah 46:9)
God is from everlasting to everlasting, with no beginning or end (Psalms 90:2), immortal (I Timothy 1:17), and does not tire or become weary (Isaiah 40:28).
He alone is the creator of heaven, the heaven of heavens, with all their host, the earth and all things therein, and the seas and all that is in them (Nehemiah 9:6)
**The Lord Jesus Christ **
The Iglesia ni Cristo believes that the Lord Jesus Christ, the Son of God (Matthew 3:17), is the one and only Savior given by God (Acts 13:23). Christ is the sole mediator between God and men (I Timothy 2:5) and the only way to God (John 14:6).
But we do not subscribe to the belief that Christ is God-Man. He is man in nature according to His own testimony (John 8:40) and the teachings of His Apostles (I Timothy 2:5; Matthew 1:18).
The attributes of a human being were found in Christ. He hungered (Matthew 4:2), thirsted (John 19:28), became weary or tired (John 4:6), slept (Matthew 8:24), and died (Matthew 27:50; I Corinthians 15:3). However, Christ as distinct from all men, is the only one who did not sin (I Peter 2:21-22; Hebrews 4:15).
He has been exalted by God and given a name above all other names, that at the name of Christ every knee should bow, those in heaven, and those on earth (Philippians 2:9-11). He has been placed by God far above all principality, power, might and dominion, and every name that is named, and all things have been put under His feet (Ephesians 1:21-22). Christ will eventually subject all His power and authority to the true God (I Corinthians 15:27-28). He had in so many instances introduced Himself as the Son of God but never did He appropriate the title “God?nor “God the Son?for Himself because He is not God but man.
The Holy Spirit
We believe that the Holy Spirit is the power (Acts 1:8) sent by the Father in the name of Christ, to teach and remind His messengers of all the things that Christ said (John 14:26).
Christ also sends the Holy Spirit to help us in our weaknesses and infirmities (John 15:26; Romans 8:26). The Holy Spirit strengthens, edifies, and comforts the Church of Christ (Ephesians 3:16-17); John 14:26). And although the Holy Spirit is a spirit, never do the Scriptures refer to Him as “God the Holy Spirit?because He is not God but one of the spirits being sent by God.
**The Holy Scriptures **
We believe that the Bible is the sole basis of faith and service to God. The Gospel is the power of God unto salvation to those who believe, for in it the righteousness of God is revealed (Romans 1:16-17). The Holy Scripture is inspired by God and profitable for teaching, for doctrine, for reproof, for correction, and for instruction in righteousness, that the man of God may be perfect, thoroughly furnished for all good works (II Timothy 3:15-17).
God has purposely hidden His words in mystery (Romans 16:25), so that men who strive to understand the Scripture through their own worldly knowledge can never come to know the truth (II Timothy 3:7). The Gospel preached by those who are not sent by God is called by the Apostles “another gospel?(Galatians 1:6-7). And the use of the Gospel which deviates from the truth or from its true meaning will ineluctably lead to perdition (II Peter 3:15-16).
