Opusculum 6 is another work of Maximus that stems from his involvement in the monoenergist and monothelite controversies discussed in the introduction to Ambiguum 31 to Thomas. Opusculum 6, “Concerning the statement, ‘Father, if possible, let this cup pass from me,’” dates to 640 or 641. By that time Maximus was thoroughly embroiled in combating monothelitism. This position – which maintained that Christ had only one will (thelēma) – grew out of the somewhat vaguer and perhaps more conciliatory monoenergist position. When Heraclius promulgated the Ekthesis in 638, the deliberately nebulous language of the Psēphos gave way to a more definitive statement of the singularity of Christ’s activity and will. Maximus had already objected to monoenergism, and now all the more strongly to monothelitism. He argued that the distinction of human and divine wills in Christ did not imply their opposition, and this claim is most tested in Jesus’s prayer in Gethsemane (Matthew 26:39–40).
