Semiahmoo Baptist Church believes in and shall “earnestly contend for the faith which was once delivered unto the saints”; which faith includes the devine inspiration of the Bible, both Old and New Testaments; the creation of man by the direct act of God; the incarnation and virgin birth of our Lord and Saviour, Jesus Christ; His identification as the Son of God; His vicarious atonement for the sins of mankind by the shedding of His blood on the cross; the resurrection of His body from the tomb; His power to save men from sin; the new birth through regeneration by the Holy Spirit; the gift of eternal life by the grace of God.
Semiahmoo Baptist Church further believes that every born again believer is sealed by the Holy Spirit until the day of redemption only because of the grace of God; the imminent, premillenial return of Christ; the ordinances of baptism by means of immersion and the Lord’s Supper in remembrance of our Lord. The King James Version of the Bible is used in all services of the Church.
