John 7:53-8:11; 2 Peter 1:1-2:1

God provided the Church with His Word which is a witness of Her Saviour that couldn't be hidden or tampered with by the hands of men. His Word is the perfect union of the testimony of God the Holy Spirit and the testimony of many human witnesses to Christ. Because of this, the Church can commit herself to trusting and submitting only to the Word that can be demonstrated as coming from Her Saviour in the presence of many witnesses.
