What a church believes says a lot about who they are. Contrary to popular opinion today which holds to the position that "doctrine divides," we believe that where there is no doctrine, there is no church (Eph. 2:20-21).
The Apostle Paul charged his young protégé Timothy to "follow the pattern of sound words (doctrine) which you have heard from me" (2 Tim. 1:13). The word doctrine in its basic sense means teaching. Thus, the Bible contains the doctrine or the teaching which comes directly from God himself (2 Tim. 3:16). The word of God contains within it the full revelation of divine truth that is essential for the believer's life and Godliness.
That's why Jesus in his High-Priestly prayer in John 17:17 prayed that his disciples would be "sanctified in the truth." He then clarifies that the truth is actually God's word (scripture). Sanctification and growth only happen when all of God's word is faithfully applied to every area of life.
At GPC, we are a Confessional church which holds to the Westminster Confession of Faith as our doctrinal treatise. We believe that this great historical work beautifully sums up the major doctrines (teachings) of the Bible as a whole. Though it is a helpful summary of Biblical truth, it should never usurp the ultimate authority of scripture itself.
