The "Damasine List" (so-called)

"Acc[ording] to E. von Dobschütz, [the Gelasian Decree/Decretal] is not a Papal work at all, but a private compilation [(e.g. 'gelehrte Privatarbeit' (Dobschütz, Das Decretum Gelasianum (1912), 250, speaking of the List in chap. 2 specifically, and not just the Decretal as a whole))] which was composed in Italy (but not at Rome) in the early 6th cent. Other scholars, while accepting this date, think it originated in Gaul."

Yet "many scholars (e.g. Thiel, Maassen, Turner, Zahn, Bardy, Di Capua) admit the possibility that [Pope] Damasus is responsible for the first part, which would have been composed at the Council of Rome in 382. . . ."

Heresy

"The formal denial or doubt of any defined doctrine of the Catholic faith. In antiquity the Greek word αἵρεσις, denoting ‘choice’ or ‘thing chosen’, from which the term is derived, was applied to the tenets of particular philosophical schools. In this sense it appears occasionally in Scripture (e.g. Acts 5: 17) and the early Fathers. But it was employed also in a disparaging sense (e.g. 1 Cor. 11: 19) and from St Ignatius (Trall. 6, Eph. 6) onwards it came more and more to be used of theological error. . . ."

Ecumenical councils

"Oecumenical Councils (Gk. οἰκουμένη, ‘the whole inhabited world’). Assemblies of bishops and other ecclesiastical representatives of the whole world whose decisions on doctrine, cultus, discipline, etc., are considered binding on all Christians. Acc. to the teaching of most Christian communions outside the RC Church there have been no Oecumenical Councils since the schism between E. and W., the last being the second of Nicaea in 787. . . .
"Seven Councils are commonly held both in E. and W. to be oecumenical. These are, with their dates and the chief subjects dealt with: (1) Nicaea I (325, Arianism); (2) Constantinople I (381, Apollinarianism); (3) Ephesus (431, Nestorianism); (4) Chalcedon (451, Eutychianism); (5) Constantinople II (553, Three Chapters Controversy); (6) Constantinople III (680–1, Monothelitism); (7) Nicaea II (787, Iconoclasm). . . ."
