From the website of the Patriarchate.
“More than 350 years have elapsed since the first publication of the so-called «Lucarian Confession». Eminent historians, theologians and researchers have tried to clarify whether Lucaris was the actual author of the «Confession» attributed to him by the Calvinists. The Patriarch himself verbally denied it on several occasions and proclaimed his Orthodox faith with his attitude and in his letters. To the end, however, Cyril did not disavow the «Confession» in writing. Successive Synods of the Orthodox Church have condemned the «Confession» as heretical and alien to the Orthodox faith of the Fathers.”
Protestant relatives of mine have actually claimed the Heretics of the early church period in a desperate attempt to prove the Church wrong. Be very careful how you justify the false doctrines of the lawyer Calvin.
Lucaris not only wrote his Confession, he eventually paid for it with his life, thanks to the ignominious counter-Reformation.
