“…second to none in its importance for the Pauline system of thought, the eschatological appears as predeterminative both [sic.] the substance and form of the soteriological.”
“It would be far more accurate to say that the eschatological strand is the most systematic in the entire fabric of the Pauline thought-world. For it now appears that the closely interwoven soteric tissue derives its pattern from the eschatological scheme, which bears all the marks of having had precedence in his mind” (Geerhardus Vos, The Pauline Eschatology, 60).
