From charity in the Biblical sense of Christian love; first used by Puritans. In early Christian tradition, Faith, Hope and Charity were the martyred daughters of Saint Sophia. The names, taken from 1 Corinthians 13:13 ("And now abideth faith, hope, charity, these three; but the greatest of these is charity") have been translated and used in many languages. The name of the sura (chapter) is one of several translations of the original Arabic.
