Ridgefield — Students at Cedar Tree Christian Classical School celebrated the Protestant Reformation of the 16th Century on Oct. 31 by dressing up as noteworthy Christians from history. For the school’s 15th annual Reformation Day celebration, many of the 160 K-12 students wore costumes to represent Christians ranging from those in the Bible to famous missionaries, according to a press release. To teach younger students about the history of the Reformation, high school-age teens created carnival-style booths and middle schoolers performed plays.
