Clement was Bishop of Rome after Peter, Linus and Cletus. He lived towards the end of the first century, but nothing is known for certain about his life. Clement’s letter to the Corinthian church has survived. It is the first known Patristic document, and exhorts them to peace and brotherly harmony.

The theological virtue of hope is symbolized by the colour green, just as the burning fire of love is symbolized by red. Green is the colour of growing things, and hope, like them, is always new and always fresh. Liturgically, green is the colour of Ordinary Time, the orderly sequence of weeks through the year, a season in which we are being neither single-mindedly penitent (in purple) nor overwhelmingly joyful (in white).
