The Shepherd of Hermas: Commandment the First

On Faith in God

First of all, believe that there is one God who created and finished all things, and made all things out of nothing. He alone is able to contain the whole, but Himself cannot be contained. Have faith therefore in Him, and fear Him; and fearing Him, exercise self-control. Keep these commands, and you will cast away from you all wickedness, and put on the strength of righteousness, and live to God, if you keep this commandment.
