Sissinios 7 was bishop of Basilinopolis in Bithynia; in 681 he attended the Third Council of Constantinople (the Sixth Ecumenical Council) and was present at two of the last three sessions (sessions sixteen and eighteen, on 9 August and 16 September): Riedinger, pp. 690-826 (= Mansi XI 616-676). His name is lost from the Greek list of subscriptions to the statement of the faith, which condemned monotheletism, but is preserved in the old Latin list printed in Mansi, where he is styled "Sisinnius misericordia Dei episcopus Basilinopoleos Bithyniae provinciae": Mansi XI 650. His name does not appear in the Riedinger version of the subscriptions to the statement of the faith at all. In the list of signatures to the Council he is styled Σισίννιος ἐλέει Θεοῦ ἐπίσκοπος Βασιλινουπόλεως Βιθυνίας: Riedinger, p. 826, line 24 (= Mansi XI 676) (the old Latin version here, printed only in the Mansi version, calls his see "Basilinopoleos Bithyniae provinciae", Mansi XI 675). In the lists of those present at each session he is styled Σισινίου ἐπισκόπου Βασιλινουπόλεως: Riedinger, p. 690, line 8, p. 760, line 15 (= Mansi XI 616, 628).

Still bishop of Basilinopolis in 692, he attended the Quinisext Council in Constantinople and signed the canons: Ohme, Bischofsliste, p. 156, no. 97 (= Mansi XI 996) (Σισίννιος ἀνάξιος ἐπίσκοπος Βασιλινουπόλεως τῆς Βιθυνῶν ἐπαρχίας).
