The beliefs of the Foursquare Church are expressed in its Declaration of Faith, compiled by its founder Aimee Semple McPherson. McPherson also authored a shorter, more concise creedal statement. We believes in the verbal inspiration of the Bible, the doctrine of the Trinity, and the deity of Jesus Christ. We believe that human beings were created in the image of God but, because of the Fall, are naturally depraved and sinful. We believe in the substitutionary atonement accomplished by the death of Christ. The church teaches that salvation is by grace through faith and not by good works. Believers are justified by faith and born again upon repentance and acceptance of Christ as Lord and king. Consistent with its belief in human free will, the Foursquare Church also teaches that it is possible for a believer to backslide or commit apostasy. The Foursquare Church teaches that sanctification is a continual process of spiritual growth. Christian perfection and holiness can be attained through surrender and consecration to God. This spiritual growth is believed to be promoted by Bible study and prayer. The Foursquare Church believes in the baptism with the Holy Spirit as an event separate from conversion that empowers the individual and the wider church to fulfill the church's mission of evangelization. The Foursquare Church expects Spirit baptism to be received in the same manner as recorded in the Book of Acts, namely that the believer will receive spiritual gifts, possibly (though not necessarily) including speaking in tongues. The evidence of the Spirit-filled life is the Fruit of the Spirit. The church believes that spiritual gifts continue in operation for the edification of the church. The Foursquare Church believes that divine healing is a part of Christ’s atonement. It teaches that the sick can be healed in response to prayer. The Foursquare Church anticipates a premillennial return of Christ to earth. It believes that there will be a future final judgment where the righteous will receive everlasting life and the wicked everlasting punishment. The Foursquare Church observes believer's baptism by immersion and the Lord's Supper or Holy Communion as ordinances Open communion is practiced. Anointing of the sick and tithing are practiced as well.
