Clement of Rome, in his First Epistle to the Corinthians, recounts in some detail the saints and heroes of the Old Testament--he doesn't use that phrase "Old Testament"--for him these saints are relevant in his day. He ends with Daniel and the Three Young Men in the Fire, then writes:
Therefore we too, brothers, must follow examples such as these. For it is written: "Follow the saints, for those who follow them will be sanctified."
No source is cited for that quotation, and the footnotes say it is "unknown." He could have just as well cited St. Paul, who wrote to the Philippians (4:9), "What you have learned and received and heard and seen in me, do; and the God of peace will be with you." It's a summons to emulate a saint.
So my question is: Who are you emulating? Who's your "saint" or godly example? And does it make a difference? And if you have none, why not?
