c.576-681. Pope from 678. At the invitation of Constantine IV, who hoped to effect a reconciliation between Western and Eastern churches, Agatho sent legates to the sixth ecumenical council* at Constantinople in 680. The legates read Agatho's letter in which he declared the inerrancy of the Roman Church and held that the Roman bishops had always strengthened their brethren in terms of Christ's injunction to Peter (Luke 22:32). He then set forth the orthodox doctrine of the “two wills.” The letter was accepted with acclamation by all present, including the emperor, but unfortunately for Agatho's interpretation of Luke 22:32 the council condemned as a heretic one of his predecessors, Honorius (d.638).
