The Creed of Jerusalem
The Baptismal Creed of Jerusalem was a sort of precursor to many other creeds that would follow and is also considered the template for most baptismal confessions. It has been used for centuries as an abbreviated creed confessed before baptism and its basic formula is still utilized today. It is dated to 350 A.D. and the original form is given to us by Cyril of Jerusalem in his Catechetical Lecture 19. It was one of the sources of the Nicene-Constantinopolitan Creed, drawn up at the First Council of Constantinople in 381.
The Baptismal Creed of Jerusalem:
“I believe in the Father, and in the Son, and in the Holy Ghost, and in one Baptism of repentance.”
