A basis of faith is a summary statement of what you believe, which is helpful for a number of reasons: convenience, conciseness, it helps to lay out where points of agreement / disagreement occur, etc. A basis of faith does not need to be written down: everyone has some kind of basis of faith, whether they know it or not! I believe that it is helpful for a basis of faith to be written down so that it can be tested against the Scriptures and correct if necessary. It is also helpful to have written down as it is easier to discern when you deviate from it.
If you want a helpful book about why creeds and confessions are important, have a read of The Creedal Imperative by Carl Trueman.
As such, I thought it would be fair to include a brief statement of faith about where UTB is coming from. I am from the Reformed / Protestant tradition within the church, which fundamentally means that I believe the Scriptures alone are authoritative for the church. I have spoken about this many times in Understand the Bible videos, for example the first part of the What is Christianity? course.
However, I do not believe that the church, as defined in the Bible, can be identified with any human institution. The church is comprised of all those who are united to Christ by faith.
I aim to speak from a non-denominational but Biblical perspective. That is to say, I do not wish to cause unnecessary division by focussing on secondary issues (e.g. the baptism of infants), I wish to focus on what C.S. Lewis called ‘mere Christianity’.
