The Instructions of Commodianus 33

O people, ferocious, without a shepherd, now at length wander not. For I also who admonish you was the same, ignorant, wandering. Now, therefore, take the likeness of your Lord. Raise upward your wild and roughened hearts. Enter stedfastly into the fold of your sylvan Shepherd, remaining safe from robbers under the royal roof. In the wood are wolves; therefore take refuge in the cave. Thou warrest, thou art mad; nor dost thou behold where thou abidest. Believe in the one God, that when dead thou mayest live, and mayest rise in His kingdom, when there shall be the resurrection to the just.
