Therefore, as God’s chosen people, holy and dearly loved, clothe yourselves with compassion, kindness, humility, gentleness and patience.
This quote (or quotes very similar) are attributed to several people. Here is one likely author.
Rev. John Watson (3 November 1850 – 6 May 1907), known by his pen name Ian Maclaren, was a Scottish author and theologian. It is thought that Maclaren was the original source of the quotation “Be kind, for everyone you meet is fighting a hard battle,” now widely misattributed to Plato or Philo of Alexandria. The oldest known instance of this quotation is in the 1897 Christmas edition of The British Weekly, penned by Maclaren: “Be pitiful, for every man is fighting a hard battle.” source
