Castlewoods Reformed Baptist Church believes that the Bible is the supreme authority in all spiritual and doctrinal matters. Yet, to make certain that there is no confusion in the doctrinal stance of the church, CBC adopted the 1689 London Baptist Confession of Faith as a tool and summary of the church's beliefs.
The following is a quote from Charles Spurgeon regarding the LBCF:
What We Believe
"This ancient document is a most excellent epitome of the things most surely believed among us. By the preserving hand of the Triune Jehovah we have been kept faithful to the great points of our glorious Gospel, and we feel more resolved perpetually to abide by them.
This little volume is not issued as an authoritative rule, or code of faith, whereby ye are to be fettered, but as an assistance to you in controversy, a confirmation in faith, and a means of edification in righteouenss. Here the younger members of our church will have a body of divinity in small compass, and by means of the scriptural proofs, will be ready to give a reason for the hope that is in them.
Be not ashamed of your faith; remember it is the ancient Gospel of martyrs, confessors, reformers, and saints. Above all, it is the Truth of God against which the gates of hell cannot prevail. Let your lives adorn your faith, let your example recommend your creed. Above all, live in Christ Jesus, and walk in Him, giving credence to no teaching but that which is manifestly approved of Him, and owned by the Holy Spirit. Cleave fast to the Word of God, which is here mapped out to you." - C. H. Spurgeon
