Let us find out what they believe.
- Catholics: Catholics share with other Christians a belief in the divinity of Jesus Christ, the son of God made man who came to earth to redeem humanity’s sins through His death and resurrection. They follow His teachings as set out in the New Testament and place their trust in God’s promise of eternal life with Him. However, Catholics also believe you pray to God in the name of human beings such as Mary and even bow down to their statues, completely going against God’s commandment not to worship or pray to any other God except Him (Exodus 20:3-5). They also erroneously beleive that a person can go to a place or state of suffering inhabited by the souls of sinners who can make amends for their sins before going to heaven but Hebrews 9:27 states that it is appointed unto a man once to die and after this the judgement.
- International Church of Christs: The ICOC is a collection of protestant evangel groups, with two important exceptions. First, the group claims that any church outside of their unified system, i.e., not under the ICOC’s leadership, is not a part of the “true church.” Secondly, they teach baptismal regeneration- the belief that water baptism is required for salvation. The ICOC believes that anyone who is not baptized is not saved and must be “evangelized” and brought into the church. Further, the ICOC teaches that the only “valid” baptism is one performed by the ICOC. No other baptism will do. Further still, the ICOC does not allow anyone to be baptized until he or she is first a “disciple” committed to the organization. The Bible, on the other hand, teaches that salvation is by grace through faith, apart from works (Ephesians 2:8–9)—including the work of baptism.
- Jehovahs Witnesses: They believe that Jesus is not God and, though divine, is not equal to God but always below God. Christ and the Archangel Michael are thought to be one and the same in the belief of Jehovah’s witnesses. They also believe, contrary to the bible in Matthew 24:35, 2 Peter 3:7-10 and Revelations 21:1, that there will be no destruction on the earth so they desire to stay on this earth forever.
- Mormons: The Christians consider God to be a “necessary being”, meaning that he cannot not exist, while all other creations are “contingent beings”. In Mormonism, by contrast, God created the universe and everything in it from existing matter. Their belief is contrary to John 1:3 and Hebrews 11:3.
- Oneness Pentecostals: The “Jesus Only” movement, also known as Oneness Pentecostalism or oneness theology, teaches that there is only one God, but denies the tri-unity of God. In other words, oneness theology does not recognize the distinct persons of the Godhead: Father, Son, and Holy Spirit. This goes against the bible in 1 John 5:7-9.
- 7 Day Adventists: Seventh-day Adventists differ in only four areas of beliefs from the mainstream Trinitarian Christian denominations. These are the Sabbath day, the doctrine of the heavenly sanctuary, the status of the writings of Ellen White, and their doctrine of the second coming and millennium.
- Unitarians: Unitarianism is a Christian religious denomination. Unitarians believe that God is only one person. Unitarians reject the Trinity and do not believe that Jesus Christ was the Son of God. Followers of Unitarianism also do not accept the concepts of original sin and of eternal punishment for sins committed on earth.
Now that we have learnt their beliefs, lets us remember that if we ever encounter them, we are not to argue with them but to always point them back to the gospel of our Lord Jesus Christ. The 10 Commandments Test will really help with that.
