The Bible is the infallible Word of God and the authority for salvation and Christian living. (See II Timothy 3:15-17.)
In water by immersion in the name of the Lord Jesus Christ for the remission of sins and in the baptism of the Holy Ghost, speaking in other tongues as the Spirit gives utterance. This constitutes the new birth.
That Jesus is the only saving name ... And whatsoever you do in word or in deed, do all in the name of Jesus.
The saving gospel is the good news that Jesus died for our sins, was buried, and rose again. We obey the gospel (II Thessalonians 1:8; I Peter 4:17) by repentance (death to sin), water baptism in the name of Jesus Christ (burial), and the baptism of the Holy Spirit with the initial sign of speaking in tongues as the Spirit gives the utterance (resurrection). (See I Corinthians 15:1-4; Acts 2:4, 37-39; Romans 6:3-4.)
