The only source of the revelation of God’s will on earth today is the Word, the Bible.
Its author is God Himself, the Holy Spirit. It is God’s Word that is our guide in building and shaping the ministry of the church, as well as the main criterion for every decision regarding the life of the church as a whole and each individual member (2 Timothy 3:16-17, Colossians 2:8, Jude 1:3).
