TPC’s Youth Group presents “A Celebration of Theodore Parker,” a play written by TPC’s former minister, Robert Haney, drawn from real letters of Parker and his contemporaries and presenting a portrait of the man and his times. The play was first performed 25 years ago, in June 1987. On this Sunday, we also celebrate our three graduating seniors: Thomas Colgrove, Rose Gallogly, and Gryphon Layne.
