1 Timothy 6:12

Fight the good fight. Literally, strive [8] a good strife. St. Paul oftentimes brings this comparison of men striving for a prize. --- And hast confessed a good confession before many witnesses, not only when baptized, not only when thou wast ordained a bishop, but by thy constancy and sufferings and persecutions, says St. John Chrysostom, thou we know not the particulars. (Witham) --- Timothy had made profession of his faith at his baptism, at his ordination, and during the whole course of a life which, through many labours and persecutions, had been dedicated entirely to promote the faith. (D. Thomas [St. Thomas Aquinas]) --- Like him let us also combat, if we aspire after the same triumph and prize.
