Well GHW, it seems to me if you are declaring a universal christian creed, you would want to recognize your competition. The oldest recognized creed is the Apostle's Creed of the 2nd -5th Century. Nicene Creed 4th century. Athenanasian Creed 5th century, Chalcedonian Creed 5th century. Book of Concord - Lutheran. Westminster, The 39 Articles and the London Baptist Confession..
Perhaps if you contrasted your creed to these creeds it would be helpful to see where your's stands by comparison.
While you are at it, please indicate what Jesus meant when He said as recorded in John 17 Jesus was praying for those who follow Him. "Holy Father, keep them safe in your name that you have given me, so that they may be one just as we are one." His prayer for believers to follow, "“I am not praying only on their behalf, but also on behalf of those who believe in me through their testimony, that they will all be one, just as you, Father, are in me and I am in you. I pray that they will be in us, so that the world will believe that you sent me. The glory you gave to me I have given to them, that they may be one just as we are one – I in them and you in me – that they may be completely one, so that the world will know that you sent me, and you have loved them just as you have loved me.
Jesus made it clear that his true disciples would not be known for their disparate theologies, their prosperity, their knowledge of the bible, their church attendance, the elegance of their unique take on the "truth" or their political allegiances. "By this will everyone know you are my disciples, if you love one another."
So it seems to me that in our ever evolving personal take on Christian "Truth" we probably should start with the validation of our discipleship - that we love one another. So what does that priority imply about all divisive creeds, confessions and self-righteous but divisive bible interpretations? Are we still in that "Just love and trust God" reality or does surrender, conversion, humility, gentleness, kindness, service and love have any priority at all?
