Symbole des apôtres
The Eastern Orthodox Church does not use the Apostles' Creed, not because of an objection to any of its articles, but because of its omissions necessary for the definition of Nicene Christianity. The Orthodox delegates at the Council of Florence (1431–1449) explicitly challenged the western tradition attributing the Apostles' Creed to the Twelve Apostles. This tradition was also shown to be historically untenable by Lorenzo Valla.
