The EOs have their tradition from the 1st and 2nd century AD and follow the Church fathers. so I don't know where you would get that idea.
1st-2nd century writings and Church fathers important in the EO Church include:
50-120 AD: Didache
80-120 Epistle of Barnabas (Clement Alexandrine & Origen used it, Jerome considered its authorship genuine & Eusebius didn't, Vulgate used it as apocryphal)
80-140 1 Clement
88-160 Shepherd of Hermas (included in Codex Sinaiticus; Muratorian fragment says it "ought indeed to be read; but it cannot be read publicly"; Clement Alexandrine uses it but notes "many people despise it")
90-150 Apocalypse of Peter (Muratorian canon has it but says some ban it from reading in church, Accepted by Clement Alexandrine, not counted genuine by Eusebius)
90-218 4 Esdras (Vulgate) / 2 Esdras (Protestant) / 3 Esdras (Slavic), including Chp 7 w/ NSRV verses 35-105 (Canonical in the Ethiopian Orthodox Bible, Apocryphal in the Vulgate, Russian, and KJV)
95-160 2 Clement
