when was the canon of the new testament closed
For the Orthodox, the recognition of these writings as authoritative was formalized in the Second Council of Trullan of 692. The Catholic Church made dogmatic definition upon its Biblical canon in 382 at the Council of Rome as well as at the Council of Trent of 1545, reaffirming the Canons of Florence of 1442 and North African Councils (Hippo and Carthage) of 393 -- 419. For the Church of England, it was made dogmatic on the Thirty-Nine Articles of 1563; for Calvinism, on the Westminster Confession of Faith of 1647.
