The First Epistle of Clement to the Corinthians

For God spake thus: Let us make man according to our image and likeness; and God made man, male and female made he them.

So when he had finished all these things he praised them and blessed them and said, Increase and multiply.

Let us observe that all the righteous have been adorned with good works; and the Lord himself adorned himself with good works and rejoiced.

Having therefore this pattern let us follow his will without delay, let us work the work of righteousness with all our strength.
