For now this is only a study topic but nevertheless I think it’s something worth thinking about...
As a matter of fact various religious groups throughout the centuries have put a lot of effort into writing confessional documents that define them regarding their religious beliefs. Sometimes their motivation was to denounce errors and to proclaim truth. However, in the end these confessional documents serve the purpose of distinguishing us from one another amongst ourselves, and even to divide us.
Hence the question: What unites us as Christians? Or yet, what is the common denominator of our Christian faith? What is the baseline under which the expression “being a Christian” loses its meaning?
I believe the Apostles’ Creed is an interesting starting point for this study:
I believe in God, the Father almighty, maker of heaven and earth;
And in Jesus Christ his only Son our Lord;
who was conceived by the Holy Ghost, born of the Virgin Mary, suffered under Pontius Pilate, was crucified, dead, and buried. He descended into hell. The third day he rose again from the dead. He ascended into heaven, and sits at the right hand of God the Father almighty. From thence he shall come to judge the quick and the dead.
I believe in the Holy Ghost, the holy catholic* church, the communion of saints, the forgiveness of sins, the resurrection of the body, and the life everlasting. Amen.
* I understand “catholic” as meaning “universal”.
And for your pleasure, here is a song by Rich Mullins that I enjoy very much.
That song was also recorded in 2010 by Brandon Heath and Third Day.
