The Statement of Fundamental Truths is a confession of faith outlining the 16 essential doctrines adhered to by the Assemblies of God USA. These doctrines are heavily based on other evangelical confessions of faith but differ by being clearly Pentecostal. Of the 16 articles, four are considered core beliefs "due to the key role they play in reaching the lost and building the believer and the church". They are the doctrines concerning salvation, the baptism in the Holy Spirit, divine healing, and the Second Coming of Christ. The Statement of Fundamental Truths has undergone several permutations since its original adoption in 1916 (when it actually included 17 items) despite common claims that it has remained largely unchanged.
