Irenaeus' "Rule of Faith"

Irenaeus was a very early Church teacher. 130 AD to roughly 202 AD is the time period in which he lived and wrote. He was a 'hearer' of Polycarp who was a disciple of John The Apostle. His generation is when all kinds of heretical and false christian teachings started to take off. His greatest works are called "Against Heresies" and in them he laid out what these false teachings are and why they are not Christian. Through this he came up with a simple summery of what exactly the genuine and true Christians beliefs are. He called it the "rule of faith"

Irenaues' Rule of Faith (180 AD):

"this faith: in one God, the Father Almighty, who made the heaven and the earth and the seas and all the things that are in them;

and in one Christ Jesus, the Son of God, who was made flesh for our salvation;

and in the Holy Spirit, who made known through the prophets the plan of salvation, and the coming, and the birth from a virgin, and the passion, and the resurrection from the dead,

and the bodily ascension into heaven of the beloved Christ Jesus, our Lord, and his future appearing from heaven in the glory of the Father to sum up all things and to raise anew all flesh of the whole human race"
