III. The ejected bishops must be restored, and the Nestorian canons retain their force.
But because we know full well that through evil jealousies the state of many churches has been disturbed, and a large number of bishops have been driven from their Sees for not receiving the heresy and conveyed into exile, while others have been put into their places though yet alive, to these wounds first of all must the healing of justice be applied, nor must any one be deprived of his own possession that some one else may enjoy it: for if, as we desire, all forsake their error, no one need lose his present rank, and those who have laboured for the Faith ought to have their rights restored with every privilege. Let the decrees specially directed against Nestorius of the former Synod of Ephesus, at which bishop Cyril of holy memory presided, still retain their force, lest the heresy then condemned flatter itself in anything because Eutyches is visited with condign execration. For the purity of the Faith and doctrine which we proclaim in the same spirit as our holy Fathers, equally condemns and impugns the Nestorian and the Eutychian misbelief with its supporters. Farewell in the Lord, brethren most dear. Dated 26th of June, in the consulship of the illustrious Adelfius (451).
