Les débuts du monoénergisme. Rectifications concernant ce qui s’est passé entre Cyrus d’Alexandrie, Serge de Constantinople et S. Sophrone de Jérusalem

The article shows that St Sophronius met Cyrus of Antioch after the Union (3 June 633) between the Chalcedonians and the Theodosians had been signed. The letter of Cyrus which Sophronius brought to Sergius of Constantinople after the failure of his meeting with Cyrus cannot be identified as the Ep. ad Sergium CP (CPG 7611) as Grumel and Winkelmann considered: it was another letter, the existence of which had already been postulated by Hefele, a short extract of which is preserved in the Acts of the Lateran Council of 649. Neither can the letter forbidding all discussion of one or two operations in the two natures of Christ, which Sergius sent to Cyrus after his meeting with Sophronius, be identified as the Ep. ad Cyrum Alex. (CPG 7605).
