Leo is said to have described mere image veneration as "a craft of idolatry." He apparently forbade the veneration of religious images in a 730 edict, which did not apply to other forms of art, including the image of the emperor, or religious symbols such as the cross. "He saw no need to consult the Church, and he appears to have been surprised by the depth of the popular opposition he encountered". Germanos I of Constantinople, the iconophile Patriarch of Constantinople, either resigned or was deposed following the ban. Surviving letters Germanos wrote at the time say little of theology. According to Patricia Karlin-Hayter, what worried Germanos was that the ban of icons would prove that the Church had been in error for a long time and therefore play into the hands of Jews and Muslims.
