Nicene and Apostles

 

I'm going to be comparing the Apostles Creed with the Nicene Creed over the next month as well as some interesting facts and meditations. Enjoy.

Apostles: I believe in God, the Father Almighty, creator of Heaven and Earth.
Nicene: I believe in one God, the Father Almighty, maker of Heaven and Earth, of all things visible and invisible.

The Apostles creed is as early as the close of the first century. It was created to be interogative as well as a profession of faith. The Nicene creed was created at the Council of Nicea in 325ad shortly after the Edict of Milan as signed into law by Constantine which legalized Christianity in the Empire.

Your medetation: why did the Nicene creed add "one" before God and "all things visibe and invisible"?
