The Apostolic Doctrine Concerning God:
There is only one God. (Deuteronomy 6:4) He is the creator of heaven and earth, and all living beings. He has revealed himself to humanity as the Father, Son, and the Holy Ghost. God is a Spirit. (St. John 4:24) He is the first and the last, and besides Him there is no God. (Isaiah 44:6) There was no God formed before Him; neither shall there be after Him (Isaiah 43:10).
Son: And she shall bring forth a son, and thou shalt call His name Jesus for He shall save His people from their sins. (Matthew 1:21)
Holy Ghost: The Holy Ghost is not a third person in the Godhead, but rather the spirit of God, the spirit of the resurrected Christ. The Holy Ghost is a Comforter that dwells in the hearts and lives of every believer. (St. John 14:16-26)
Water baptism is an essential part of the New Testament church. Water baptism is to be administered only by immersion. Paul stated, “we are buried with Him by baptism into death” . . . (Romans 6:4)
Jesus’ death, burial, and resurrection are applied to our lives when we experience New Testament salvation. Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. (Acts 2:38)
Speaking in tongues mean speaking miraculously in a language unknown to the speaker, as the Spirit gives utterance. Tongues are classified in two ways. First, speaking in other tongues as the initial evidence of the baptism of the Holy Ghost and secondly, the gift of tongues as mentioned in I Corinthians. Speaking in other tongues as the Spirit of God gives utterance is a manifestation God has given as the witness or sign of the baptism of the Holy Ghost.(Acts 10:46) It was prophesied by the prophet Isaiah as the rest and the refreshing (Isaiah 28:11-12), foretold by Jesus as a sign that would follow believers of the gospel (St. Mark 16:17), and experienced by Jews and Gentiles alike.
Secondly; the gift of diverse kinds of tongues, mentioned by Paul in I Corinthians 12:1-10. Paul stated, forbid not speaking in tongues. (I Corinthian 14:39)
We are commanded to live soberly, righteously, and godly in this present world (Titus 2:12) and warned that without holiness no man shall see the Lord. (Hebrews 12:14) We must present our bodies a living sacrifice, holy, acceptable unto God, which is our reasonable service and be not conformed to this world: but be transformed by the renewing of your mind. (Romans 12:1) It is quite impossible to live a holy life without the Holy Ghost. Ye shall receive power, after that the Holy Ghost is come upon you. (Acts 1:8)
Divine healing was purchased for us by the blood of Jesus Christ, especially by His stripes. (Isaiah 53:5) Jesus went everywhere healing those that were sick, and He commanded His disciples to do the same. (St. Matthew 10:8) Jesus stated, “That they shall lay hands on the sick and they shall recover”. (Mark 16:18)
Second Coming of Christ:
Jesus Christ is coming back to the earth in bodily form, just as He went away. (Acts 1:11) For the Lord himself shall descend from heaven with a shout, with a voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. (I Thessalonians 4:16-17)
There will be a resurrection of all the dead, both just and unjust. I saw the dead, small and great, stand before God . . . and the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them. (Revelation 20:12-13)
It is appointed unto men once to die, but after this the judgment. (Hebrews 9:27) We must all appear before the judgment seat of Christ; that everyone may receive the things done in his body, according to that he hath done, whether it be good or bad. (II Corinthians 5:10)
