{58} Note the plain statement that the emperor has no authority in ecclesiastical matters. Observe also the general tone of the whole letter.
{59} This is equivalent to the excommunication of the emperor. But as Gregory’s authority was not recognized in Constantinople, his excommunication of the emperor would not be observed.
{60} The first six general councils of the church here referred to were (1) Nicæa, 325; (2) Constantinople, 381; (3) Ephesus, 431; (4) Chalcedon, 451; (5) Constantinople, 553; (6) Constantinople, 681.
{61} The text of this passage, as Migne has it, is perhaps corrupt; its meaning, at any rate, is obscure. We have given the only reasonable interpretation that seemed possible. Apparently the pope agrees to assume the responsibility for the destruction of images in the past, if only the emperor will accept the papal view and cease from his opposition to images in the future.

See introductory note to [no. 41].
The pope [Gregory III] made a decree in the council that if anyone, in the future, should condemn those who hold to the old custom of the apostolic church and should oppose the veneration of the holy images, and should remove, destroy, profane, or blaspheme against the holy images of God, or of our Lord Jesus Christ, or of his mother, the immaculate and glorious Virgin Mary, or of the apostles, or of any of the saints, he should be cut off from the body and blood of our Lord Jesus Christ. And all the clergy present solemnly signed this decree.
