Konstantinos 18 was bishop of Barata in Lykaonia; in 681 he attended the Third Council of Constantinople (the Sixth Ecumenical Council) and was present at the last eight sessions (sessions eleven to eighteen, from 20 March to 16 September); at sessions sixteen and eighteen he represented bishop Paulos 6 of Ikonion and he also signed the statement of the faith and the acts of the Council on his behalf: Riedinger, pp. 406-824 (= Mansi XI 460-672). In the subscriptions to the statement of the faith, which condemned monotheletism, and to the Council, he is styled Κωνσταντῖνος ἐλάχιστος (Riedinger, p. 824, line 11 (= Mansi XI 672) has: ἐλέει Θεοῦ) ἐπίσκοπος τῆς Βαρατέων μητροπόλεως (Riedinger, p. 824, line 11 (= Mansi XI 672) reads: πόλεως) τῆς Λυκαόνων ἐπαρχίας καὶ τὸν τόπον ἀναπληρῶν Παύλου τοῦ ἐπισκόπου Ἰκονίου (Riedinger, p. 824, lines 12-13 (= Mansi XI 672) reads: ἐπέχων Παύλου τοῦ ἁγιωτάτου μου ἐπισκόπου τουτέστι μητροπολίτου Ἰκονίου): Riedinger, p. 782, lines 23-24, p. 824, lines 11-14, cf. p. 893, lines 1-3 (= Mansi XI 644, 672, cf. 692).

The old Latin version printed in Riedinger, p. 783, line 23, calls him "episcopus Baratae ciuitatis Lycaoniae regionis et locum exhibens Pauli sanctissimi metropolitani mei Iconii metropoleos". In the lists of those attending each session he is styled Κωνσταντίνου ἐπισκόπου Βαράτης: Riedinger, p. 406, line 26, p. 520, line 15, etc. (= Mansi XI 460, 521, etc.) (at Riedinger, p. 686, line 11, p. 756, line 17 (= Mansi XI 613 and 628) the words ἐπέχοντος τὸν τόπον Παύλου ἐπισκόπου τοῦ Ἰκονίου are added).

Konstantinos 18 was among the signatories to the copy of the definition of the faith sent to the bishop of Rome, Agatho 1, still representing Paulos 6: Riedinger, p. 893, lines 1-3 (= Mansi XI 692). His name occurs in the list printed in Riedinger, p. 734, lines 5-7 (= Mansi XI 696).

Still bishop in 692, Konstantinos 18 attended the Quinisext Council in Constantinople and signed the canons: Ohme, Bischofsliste, p. 166, no. 190 (= Mansi XI 1004) (Κωνσταντῖνος ἐλάχιστος ἐπίσκοπος πόλεως Βαράτων τῆς Λυκαόνων ἐπαρχίας).
