The International Church of the Foursquare Gospel affirms that the Bible is the inerrant and infallible Word of God — without error in all that it asserts, fully reliable and authoritative for matters of faith and practice. The Declaration of Faith affirms Scripture as the ultimate authority, written by the inspiration of the Holy Spirit, and as providing everything necessary for salvation and Christian living.

The Church's understanding of inerrancy includes the original manuscripts and the transmitted biblical text as sufficiently reliable for all purposes of faith and practice. Scripture is to be understood according to its literary forms and historical context, but it is fully trustworthy and authoritative. Inerrancy undergirds the Church's confidence in Scripture as the supreme standard for doctrine and Christian conduct.
